JOB CONTROL DEFINITION

All new work taken on by PDS must be controlled, to make sure that the customers brief is fullfilled, and that the job is costed and invoiced. To make sure all these processes happen, a job control database is used. This database is used to do the following: Allocate ‘Quote’ and ‘Job’ numbers Log the customer requirements Calculate quotations Measure the time taken to complete individual tasks Log total ‘man hours’ for a job Record Invoice Date and Due Dates so that invoices can be progressed. This database in maintained with the aid of the Timesheet spreadsheet whose purpose is to record daily time allocation PROCEEDURE Job Control Database Quotation: 1. Take out a quotation number. This stars a new entry in the database 2. Select the customer from the pull-down menu, or add a new customer to

the Customer database, and then continue the above. 3. Fill out the section: ‘Details of Job Quoted for’, filling in the estimated

timings in the Column: ‘Time Est.’ 4. In WORD, use ‘File, New’ to find the Quotation Template. Fill this out from

the information entered in the database. Print a copy of this and send it to the customer through the post. (An electronic copy can be sent by Email).

Job Control 1. If the Customer accepts the quotation (and the PDS ‘Terms and

Conditions’), take out a Job number on the same database entry and fill in the Order Date. A Customer Order number may also be added below if available.

2. The Job will be in progress when sufficient information has been received from the Customer.

3. As each section of the job is complete, fill out the actual timing. This enables accuracy in future quotations and warning of cost / time over-run.

4. When the job is complete, an invoice will be sent to the customer as soon as possible, and the date of sending is recorded. The Due Date will be 30 working days from the date of Invoice.

5. When the Invoice is paid, the final entry is made for ‘Date Paid’. That Job is now closed.

6. Any further work from the original remit, will require a fresh Quotation and job entry.

DESIGN CONTROL – PROJECT FILING SYSTEM DEFINITION This section defines the Project filing systems. PROCEEDURE All projects are structured using the ‘Project Filing Template’ located in the Customer directory. The structure of the project file is as follows: Assembly BOM Data-sheets Gerber Data Mechanical PCB Release Schematic The project directories are defined as follows: Assembly All Assembly drawings and data required to assemble the Printed Circuit Assembly (PCA). This directory will contain and Archive directory for filing previous versions of the file. BOM Bill of Material required for PCA Build. This will be structured according t the Customer requirements. This directory will contain and Archive directory for filing previous versions of the file. Data-sheets Any Specific Component data sheets used for a particular project. Copies of the data sheets are put in the PDS Data Library for use in other projects, when the Project file is closed. Gerber Data This is an optional storage place for gerber data, should it be required. Gerber data is normally released to the Customer, in which case it will be stored in a release file RELddmmyy. This directory will contain and Archive directory for filing previous versions of the file.

DOCUMENTS AND NUMBERING DEFINITION Each new job will have a unique number which keys all the related documents together. The process begins with the Quotation. There may be a number of quotations which never tern into a job, however, since jobs are filed by Project, unused numbers do not present a problem. All quotations are files in the Quotation directory for future reference. All Invoices and Receipts are Files under the Invoices directory. All other documents are filed under the relevant ‘Project’ directory. Number format Definition Document Type PDSC-xxx Customer No. Ref. No. PDSQ-xxx Quotation No. Word Doc.

QUALITY CONTROL - DEFINITION In order to ensure the quality of Designs done by PDS, the Quality Manual (in Appendix 1 defines procedures which will be followed in order to ensure that work leaving PDS is of a satisfactory quality, and that remedial action is taken if there are errors. Customers will ask PDS to design Printed Circuit Boards and mechanical items of various sizes and complexity. Design tasks may vary from mechanical component drawings and the digitising of very simple PCB’s (where the minimum of documentation is supplied, and the minimum of documentation is required to meet the customer requirements) to complex Multilayer designs. Whilst PDS had tried to put forward guides like the Design Check List, most customers just want a straightforward design with the minimum of input from themselves. As a result, the Design Check List will only be maintained as a Guide with PDS recommends that it’s customers use when checking their drawings and designs. Quality Disclaimer: Whilst every effort is made by PDS to produce designs and documents to the very highest quality, it is incumbent upon the customer to check all designs produced by PDS. PDS will therefore not be held liable to faults, design errors; draughting errors, manufacturing errors, non manufacuturability of any design done by PDS. PDS will also not be held liable or responsible for any losses, consequential or otherwise resulting from any draughting, drawing, incorrect component choice or design errors done by PDS. This is explicit and implicit in the Terms and Conditions publicised in Quotations and Invoices issued by PDS. See Appendix 1 Quality Manual for details of quality processes and procedures.

Definitions of Quality guidelines; checks and methods used during the design process: Checking CAD Data: The Bill of Materials (BOM): is checked against any BOM or component listing supplied by the Customer. Schematic: The Schematic is checked against any Schematic drawings supplied by

the customer, and any changes requested by the customer (by Email or Fax).

Design for EMC: This includes Presence and position of decoupling; separation of Analogue and Digital grounds and supply rails & adequate grounding of high frequency devices. Design for Test: The Customer should have made it clear whether Full Nodal; In-circuit or Functional testing is required. PCB Layout: The PCB Layout is checked against any information; drawings; Gerber data or requirements supplied by the customer. Other parameters to check in the PCB Layout: Full Netlist check: back to the originating Schematic / Netlist. Continuity Check: based on the Schematic / Netlist. Spacing Check: According to the Rules table set-up for this job. Some jobs will require ‘exceptions’ to make the customer aware that the job can still be manufactured, but some rules table requirements have been compromised to order to meet the customer requirements. E.G.Track to track or Pad to Pad rules are showing an error on a fine pitch device which has tighter requirements than the rest of the PCB. Design for EMC: This includes Presence and position of decoupling; separation of Analogue and Digital grounds and supply rails; adequate grounding of high frequency devices; tracking of devices according to guidelines if supplied; tracking of RF circuits in an appropriate manner etc.

PDS

High voltage clearance requirements: Additional routing for air-gaps may be required. Spark Gaps may be needed – grounded separately back to the PSU. No sharp track edges in the proximity of the HV clearance areas. Final Checking of this will be carried out by the Customer. RF Emissions: Provision of RF screening or split plains; additional decoupling; R/C terminations may be required to achieve emissions requirements. Final Checking of this will be carried out by the Customer. RF susceptibility: This may require the addition of grounded guard rings; additional plains; screening etc. Final Checking of this will be carried out by the Customer. Design for Test: The Customer should have made it clear whether Full Nodal; In-circuit or Functional testing is required. Checks should be made to se that the particular requirements have been met. Final Checking of this will be carried out by the Customer. Design for Manufacture: This includes all design rules supplied by the relevant PCB supplier, for clearance; acid traps; track shrinkage. Design for Assembly: This includes all design rules supplied by the relevant OEM; CEM; Assembly house. Specification of the PCB for manufacturing. This will include Layer stack-up; manufacturing laminates and chemicals (if specified by the Customer); surface finishes etc. Gerber Data: When the Gerber data has been generated, the gerber should be imported into a ‘gerber viewing’ tool e.g. Gerbtool; CAM350; ViewMate; GC Preview for additional inspection.

RELEASE TO CUSTOMER DEFINITION This procedure documents the release of partially completed and completed information to the customer. There is no differentiation between partially completed or completed data. The end customer will be responsible for the administration of all data received from PDS. PROCEEDURE All information releases to Customers are in electronic form unless specifically requested otherwise. The electronic release of information will primarily be by Email, in the form of a Zipped attachment, however, CD or 3 ½” disk are an alternative. Data which is released to the customer, is filed in the ‘Release’ directory of the Project file. Each release directory will be labeled RELddmmyy (day, month, year), eg. REL020501. In this way all releases are recorded by date. It is not expected that there would be more than one release in a day, but should this occur, the addition of an index on the end should be sufficient to indicate this. The Release directory may contain one or more files. For ease of sending the data, it is expected that the files will be in a compressed or Zipped format. Example:

REL010501

Deliverables: Gerber Data CAD files Data Sheets (if applicable) Related drawings (if applicable) CD containing the complete Project File, when the project is complete.

Quality Control DEFINITION This section details the procedure for Quality Assurance, to ensure that work leaving PDS is of a satisfactory quality, and that remedial action is taken if there are errors. The software is assumed to the AutoCad and PADS Power-PCB and CAM-350 unless otherwise stated. 1) DESIGN PROCEEDURE To ensure that Jobs leaving PDS is of the highest Quality, the following guidelines should be used. (see checking guidelines see page 14). a) Checking CAD Data: The Bill of Materials (BOM): is checked against any BOM or component listing supplied by the Customer. Drawings: The drawing or drawings are checked against any drawings sketckes or

diagrams supplied by the customer, and any changes requested by the customer (by Email or Fax).

Schematic: The Schematic is checked against any Schematic drawings supplied by

the customer, and any changes requested by the customer (by Email or Fax).

PCB Layout: The PCB Layout is checked against any information; drawings; Gerber data or requirements supplied by the customer. Other parameters to check in the PCB Layout: Full Netlist check: back to the originating Schematic / Netlist. Continuity Check: based on the Schematic / Netlist. Inner and outer layer conectivity and continutiy. Spacing Check: According to the Rules table set-up for this job. Some jobs will require ‘exceptions’ to make the customer aware that the job can still be manufactured, but some rules table requirements have been compromised to order to meet the customer requirements. E.G.Track to track or Pad to Pad rules are showing an error on a fine pitch device which has tighter requirements than the rest of the PCB.

2) DATA OUTPUT a) CAD / CAM Software Installation Procedure (Power-PCB) The CAM Device dialogue box, under the section 'Advanced', will have the following boxes ticked: Units: English Digits: L=3, T=5 Coordinates: Absolute Zero Suppress: leading Output format: RS274X Fill & Macro: Fill Mode: MUST NOT BE TICKED, Use Aperture Macros: Ticked All other areas are Default. b) Gerber Data: When the Geber data has been generated, the gerber should be imported into a ‘gerber viewing’ tool e.g. CAM350 (or alternatively: ViewMate; GC Preview). Layers of data may have to be ‘aligned’ in the software. c) Typical checks would be: All data should be present to facilitate the manufacture of the PCB. If

necessary a separate Mechanical drawing should be translated into gerber format, to include mechanical requirements like: internal routing details, break-off details or panelisation requirements.

Data in RS274x format Pad and track sizes are as specified in the PCB layout. Alignment of ‘peelable’ masks. Legend infringements onto solder pads. Correct reproduction of ‘copper pours’ and automatic thermal or electrical

plain generation. Any other details which are manually constructed in the CAD, for electrical

or manufacturing purposes. d) Additional Checks: All Gerber data generated by PDS will be inspected using the following method, prior to being issued to the Customer or Production: i) Gerber will be inspected as 'electrical layer pairs'. This is applicable to

2 sided and multilayer PCB's. For multi layer PCB's, this will mean either 'signal to ground' or 'signal to VCC' planes. Objective: To search for pad and vias connected to the EMC planes by copper flooding, and not by thermal relief's, which are not specified in the original CAD.

ii) Exceptions to this rule. For 'ultra miniature designs where 'via flood-over' is deployed as part of the design. In this case, this should be checked with respect to the original CAD Data.

Objective: To search for pad and vias connected to the EMC planes by copper flooding, which are not specified in the original CAD.

3) MANUFACTURERS FRONT END INSPECTION: The purpose of the PCB Manufacturers ‘Front End Inspection’ is to check for manufacturability of the PCB prior to panelisation, and the generation of the Drilling and Routing data. This process cannot be relied upon as a backstop for problems. The Gerber Front End department is usually under pressure, especially for short delivery times.
