HuaWei P10 Cellphone Teardown Summary

Through-out the disassembly process of the Huawei P10 cellphone we identified a total of 24 fasteners. The battery and most of the flex cables are held with double-sided adhesive tapes.
Below are certain alternatives featuring several PEM® fasteners that can help achieve better functionality and cost savings.

MicroPEM® Screws

As an alternative approach, all of the micro screws can be replaced by PennEngineering® manufactured micro screws.
PEM has license with MicroStix®, Torx® and Torx Plus® driver and self-tapping thread patent as like TAPTITE®,
FASTITE®, REMFORM® and REMFORM F® with different design solutions.

TackSert® Pin

All of the M1 screws that are used to fix & connect the keyboard with the main aluminum chassis
body can be replaced with PennEngineering® TKA™/TK4™ microPEM® TackSert® Pins. Press in installation
will be quicker than regular turn-in with screws. The specific part is ideal to replace fasteners in
applications where disassembly is not required.

PEM® microClip™ Fasteners

The micro Clip™ Fastener can replace a threaded hole and screw, thus eliminating the need for loose
hardware, while providing a permanent press in solution with clamp load.
The micro Clip™ Fastener also eliminates the need for tapped holes, or mating clinch hardware.

MSIA™ microPEM® Inserts For Plastic

The brass insert can be replaced by Type MSIB™ microPEM® Brass Inserts from PennEngineering®.
The parts provide reusable metal threads to attach plastics securely in compact electronic assemblies.
The inserts install permanently where designed into ABS, polycarbonate, and other plastic substrates
by pressing them into the host material using ultrasonic equipment or thermal press. The new MSIA series
made of Aluminum alloy with different sizes and types offer a light weight, lead-free alternative.

TackScrew™ Fasteners

All of the M1.4 tapped internal threads can be replaced with the use of TS4™ microPEM® TackScrew™
Fasteners. The microPEM® TS4™ enables cost effective sheet-to-sheet attachment by simply pressing
into place and can be removed by unscrewing, similar to original threaded fasteners.

TackPin® Fasteners

At the bottom of the main aluminum chassis body, four leaf spring type contacts function as terminals
for conductivity purposes. The contacts held by four sheet metal parts are welded on the main aluminum chassis body.
All of the welding spots can be replaced with PennEngineering® TA™/T4™ microPEM® TackPin® Fasteners. This solution
enables sheet-to-sheet attachment, replacing costly screw installation in applications where disassembly is not required.

TackSert® Pin

At the bottom of the main aluminum chassis body, four leaf spring type contacts function as terminals
for conductivity purposes. The contacts held by four sheet metal parts welded on the main aluminum chassis body.
In this case, PennEngineering® TackSert® fasteners can be used in replacing the welding spots.
This however is a permanent connection and can’t be reworked. The press-in installation will be more time effective compared to regular screws.
