Fixed my new broken chinese keyboard
Chinese Blue Mechanical Keyboard Switches.
A dozen mini-screw attachments, 5 regular, the rest of which I got to with a Chinese mobile phone repair kit. (Some 30 or so usual screw-type fittings in today's micro and otherwise manufacturing jigsaw fits.) Pulled it apart, two pieces with many interlocking plastic joints, somehow managing not to destroy the keyboard case cover. I managed not to swear, and the Gods of Graces were probably not offended. Plugged the "bare boned" keyboard into a spare USB port, two keyboards running, and variously torqued on the offending individual's keyswitch housing while activating its switching mechanism. Became evident of a cold solder joint intermittency, a QC issue, and a whole lot less work required of me, than microsoldering in and out two whole keyswitches and associated LED connections. I fixed with the Chinese keyboard a Chinese copyrighted "Every Man Woman" soldering station. Including the Chinese mobile phone disassembly kit, for under $20 of Chinese tools. Warning: Do not try that on your own under the New President Trump Regime. Chinese Cree hi-intensity LED flashlight, Chinese x30 jeweler's inspection loop, large x10 6" overhead magnifier desklamp, Chinese, all are optional for the true sense of a Chinese sweatshop, on or nearby the equator, without air conditioning: Get in and out quick, or wrap up with a towel around your neck before profusely dripping if you can't take heat.

Resoldered both and seems repaired, as does the first re-solder, which is also holding for good operation. These Chinese keyswitches are OK. It's the soldering that's crap, wherever that occurred. Hardly any, a miniscule amount of solder splatter on the board...looking for handiwork involved. Seems it would be machine/robotic soldered. Looking over the actual two-prong keyswitch contacts, I'm not so sure about an extent of manual soldering involved. The contacts, a lot to most vary to the extent of very little solder covering those keyswitch pins. The rest of the board, LED and other junction/components, contact-traces are too small to be feasible for hand-soldering. Seems it then indicates stages. Everything up to a point machine-production soldered, and then, possibly in my case, machine production of keyswitch contacts may be spotty, so it's gone over, scabbed by human corrective soldering. Not conclusively by any approximation to QC. That's three faulty solder keyswitches and could very well mean more on the way. The plus is that fixing the keys is minor, not beyond basic soldering proficiency, provided it stays that way, a little tedium here and there, and nothing more fails beyond that skill level. |
