First taste customized keyboard - KP group 87 kit custom process blueprint
Reasons to purchaseCost-effective, suitable for the first time to experience customized keyboard
Appearance GalleryJust after the New Year, it was just the year of the Burning Star, thinking of creating a keyboard for yourself. Looking for a few days on the Internet, because it is the first time do-it-yourself group keyboard, for the more expensive group buying kits are still not dare to start, but also feel that nowadays there is no suitable group purchase kit. After some comparisons, the final selection of a cool product family production kits, plastic shells, practice, with a good price. The following words do not say much, the process of drying a few pictures it.
Early Sunday morning gave up the opportunity to sleep late, excitedly took out the kit to start the previous few days. Due to the failure to find a suitable workbench, simply sit on the ground and start working! The first step is of course the upper axis. Because the original shaft price is relatively expensive, and it is the first time that you do it yourself, you have chosen a G-axis with a higher cost performance. My suggestion here is that when the shaft is on the shaft, it must be heard when the shaft is stuck into the positioning plate, so that it is completely stuck, so that accidents occur during the subsequent welding.
This is a picture of the axis completely finished. I chose the red-and-yellow axis, and the red axis was selected in the middle typing area for everyday use. Because the heart always has a special feeling toward the blue axis, the blue axis is selected in the large key position, F area, and digital area. After completing the axis, it must be reversed to check whether all the axle pins have been inserted into the PCB's pads and exposed outside. If there are individual shafts that are not exposed, personal advice is to make them all before soldering, so as not to weld half of them and find that the shafts are not exposed. This is a bit more troublesome. In addition, on the passage axis such as the blue axis and the tea axis, it is confirmed that there is no smell axis before the upper axis. It was found that there was a stinky shaft when the welding was done. At this time, when the shaft was replaced, there would be unnecessary trouble.
The following welding began, directly padding a carton open engage.
The middle of the welding link due to two hands work, inconvenient to take pictures, soldered directly on the good picture.
Upper shell.
Keycap. The key cap that did not come with the hand was only a set of large black L sidecuts.
I chose the G-axis, which is closer to the original axis. It's not bad. There are several suggestions for the younger partner:
The first is that when buying a soldering iron, besides the tin wire in the soldering iron set, buy a little more, because I found that such a 87 down, the tin wire in the set is not enough, but fortunately, the customer service reminded to buy a little more, of course Everyone is different.
When I bought it, I bought a test-welded board. I was afraid that I could not buy two. In fact, one was enough. Now I practiced my hands before I started. Like my hand-wrecked party, I probably welded a dozen of them. about there.
Then, during the soldering process, when the solder wire comes into contact with the soldering iron and begins to melt, it is necessary to continue to feed the solder wire forward so that more solder is melted into the solder pad so that the solder joint is full. Do not wait for the tin wire to melt. To put aside aesthetics, I would rather not have more or less, and avoid the situation of the Weld.
These points are a little experience that I summarized during the welding process.
In this process, as a remnant party, the individual felt that the welding process was not as difficult as he had imagined. Basically, he would try several times. There was no situation that could not be triggered during the testing process, and he was lucky. The only thing that was discovered was that one axle had forgotten to weld. In twenty years, carelessness hasn't changed. Because there was no light to buy this time, the light could only wait for the time to get it free. This born year, I feel like I have fallen into a customized pit.
