ThinkPad X1 Carbon (2016) Laptop Overview

2

The Lenovo ThinkPad X1 Carbon (2016) features a carbon-fiber

reinforced chassis and magnesium body with a semi-rugged design and large 14-

inch display.

The laptop is lighter (but larger) than ultraportable competitors like the HP

EliteBook Folio 1020 and the Apple MacBook Air 13-inch.

microPEM Micro Screws

PennEngineering has license with

Torx®, Torx Plus®, and Phillips®

Drive System and has capability to

do Zinc, Nickel and Zn-Ni plating

with different color.

PEM can provide existing

micro screws for the applications, no

change to the design.



microPEM Micro TackSerts®

The TackSert® fastener is released for use in

metal, die-cast or plastics.

This is a one-time, permanent use, fastener.

The keyboard sub-assembly may not need to

be removed.

Currently tapping magnesium chassis and

threading micro screws into the tapped holes.

TackSerts eliminate the tapping step and

replace the screws. To be installed with axial

pressure for a lower total installed cost.



microPEM Micro SI

PennEngineering can provide existing

micro brass inserts for the applications,

no change to the design.

PennEngineering offers MSIB fasteners.

Symmetric, piloted design for ease of

installation and handling.

Can be installed by heat-stake, ultra-sonics

or cold-press.

Symmetric, piloted design for ease of

installation and handling.

Aluminum option for weight reduction.



microPEM Micro SCB/SCBJ

Micro versions of SCB and SCBJ can be

used as a replacement for screw-washer

assemblies that hardware be

constrained.

The SCB and SCBJ offer an economical

solution for retained screws.

The SCB and SCBJ will provide axial

float, meaning it can move up and down

once disengaged from the mating

hardware without forcing the joint apart.

The SCB and SCBJ can be used to jack,

or force apart, the assembled joint by

turning out the screw.



Conclusions and Summary





Conclusion

Detail slidee – Copy and use for details. Summarize the findings and alternate

solutions.

There are 14 different types of screws, using 3 different driver

sizes. Also there are 138 tapped holes and 10 brass inserts in this laptop.

PennEngineering can provide the screws and inserts currently used with no

change to the design.

When and where possible, using one common driver size or type

can reduce assembly times and costs. Consolidation of screw sizes and

lengths will also benefit the manufacturer.

There are cost savings opportunities by changing many of the

threaded joints to TackSerts. 56 pierces of M1.2 x 2 screws can be replaced

with microPEM Micro TackSerts® .

Replacing the 56 pierces M1.2 threads in the magnesium chassis

with unthreaded holes would result in substantial cost saving opportunities.

In total 13 sets of screw-washer assemblies be used for screws can move

up and down once disengaged from the mating hardware without forcing the

joint apart. As a possible solution, Micro versions of SCB and SCBJ can be

used as a replacement for screw-washer assemblies that hardware be

constrained.
