Sasha, A standard RS-232 cable with the proper connectors would work. If you want you can make it. Normally the PC will have a DB-9 theses days so the wiring would be PC Machine DB-9 DB-25 2------2 3------3 5------7 Good

OK I am counting someone knowing this. True or False, if my touch-up operators touch-up the smt solder joints too many times will this make the joint weaker? if yes why? and what happens to my intermetalic layer? I have insisted if it looks good don

It's been a while but I believe we did this and it'll work (misspicks WILL go up though). I would make a quick test program and pick 50 or so parts from a feeder and place on a board with sticky tape. Placement won't really be the issue, just pick up

John, We tape (usually high temp tape) flex to a fixture (usually 0.090" piece of bare FR4). We make an outline on the fixture to get a rough location then use fiducials on the flex for alignment. Print, place, reflow, cool, remove flex. When the

no...its losing its position and it homes ok so the sensor is not the problem.....there is a mod code that sets the illumination level for the quad align....make sure that is at 200 or higher. You may want to change the qa card if you have another on

I agree with dave. Two things prevent oders from drains. The "P" trap and the celing or roof vent. If the system is sealed from the pump on then it should run thru a "P" trap this prevents vapors from comeing back thru the pipe. To make sure suction
