D. 先進的測試確認與修補都由技術人員在 CAMERA Workstation 上執行.由 key- board 或 mouse 來 移動 x,b 座標,多層板各層次之線路以不同顏色重迭顯示 在螢幕上,因此找點確認非常簡易. I tried pushing using a rolling pin as before, so or tossing the panel every minute. I'd better chance in this way but ran out of double sided table before outcomes that are fully successful could be achieved by me. Blend the chemicals into the plastic container you will do the etching in. Make merely etchant to cover the panel. Agitating the etchant aids etch the table smoothly and regenerates the etchant by oxidizing Cu+ ions. Remove the board when absolutely etched and wash it to rinse the etchant off.
PCB hosts the largest nightclub while in the U.S. - Membership Vela with Top40 and automated lamps. Since we've observed every pin's function, let us see how it's set to-use nearly and style an enterprise together with the SG3525. I have some pictures Express PCB of a completed variable (500-2000vdc) push pull routine, nevertheless they don't show underneath aspect of the circuit panel or examine the ideas involved with the calculation for your transformer.
This board includes a trace on the bottom-left hand-side that is hardly open to the perimeter and a couple of little overlaps that need scratching out. If you consider you're accomplished positioning, hold the board up towards the lighting to check for pockets that are missed. You're able to exercise phenolic table with parts that are broken, nevertheless it is tougher todo properly and the exit openings will have a tendency to splinter. Here-you can see that I drilled the very best area of the board alright, subsequently broke the touch, resulting on the board's rest in sloppy exit holes.
