I had no idea what this thread would result in.... But, since we are on the "made in China" kick... There is serious immitation going on, that is true. But that will not be the case long term. There are already companies innovating, there is techn

The Chinese make lots of things well, and a few percentage of things badly, as do many companies in Europe, US etc. However... as China is so large, that small percentage equates to a lot of product. Just do your homework on any equipment before y

Dear all, I have an issue here where we found BGA crack. Understand from friend, we need to study any possiblity of our own jig or fixture cause this problem via strain gauge measurement..My question: Is there any standard @ specification establish

The ONLY (unlikely) cause I could think of is if you are pushing the component into the solder, ending up with more solder on one side than the other. Why do you think it is the volume of solder that is causing this? By the way, there are "low tomb

Dear all, I'm having a friendly discussion with our chief manufacturing engineer. To our PCB suppliers we specify the use of "chemical gold", imo this means we use ENIG, Our boards are all copper under the solderresist which imo further confirms we

Chemical gold is a poorly defined [very sloppy] term that means various thing to different people [as you've demonstrated]. Commonly it is either: * ENIG: 5�m Ni, 0.1�m Au * Immersion gold "Autocatalytic chemical gold plating" - Refers to "electrol

Lou, You should look at the ERSA/Modus AOI System! The Modus AOI uses a high resolution industrial scanner rather than a camera mounted to a gantry. It's way faster (12 seconds for whole board ) and can do everything that a camera can do and more

Lou, There's nothing like working with it yourself. We went through this exercise several months ago. We evaluated MIRTec, YESTech, and MVP. We were looking at benchtop units, so all 3 companies were willing to send in a "demo" unit for 3 weeks.
