PCB Making-Part 5-Photo Resist Method of Etching a Printed Circuit Board HD
Part 5 in a series of informative how-to videos of my personal experiences with photo resist etching method of making precision printed circuit boards at home While designing and building my first prototype of a BLDC Hub Motor Controller board for my e-bike, I documented the whole process on video from start to finish which you can now watch in HD 720p. In this part I show you the process of tin plating the copper clad board after etching. Tin plating while help you when you got to solder and will stop copper from oxidizing. I use a plastic developing tray Yankee 8"x 10" AgiTray. Pour the Liquid Tin solution into the smaller tray. Make sure you have removed the resist coating and the copper traces are very clean. Submerse the board copper side up in the tin plating solution. Wait approximately 15-30 minutes for the solution to work. Liquid Tin can be reused many times . In the next video I will show you how to drill out all those holes on your circuit board. Check it out. http://www.youtube.com/watch?v=HKl8ueBYMCs The last part in the series shows the completed controller as well as a few other PC boards made including CNC stepper motor driver and a couple other neat electronic projects I have built to date. ©Copyright 2010 D.C.
