Do you bond with Al or gold wire? What happens if the Ni is over 150 microinches? Thickness of nickel is one those things that we have not been consistent with. The industry seems to pretty much universally call for 100-200 microinches. Our old board

Not sure how anyone could pretend to "ballpark" a cost for a board, regardless of size, especially in small quantities. You might need 10 assemblies, but the MOQ for your main component might be 100, 200, 500, 5K pcs. Makes me laugh every time I

Does anyone know if I will have problems soldering surface mount components to an all hard gold plated PC board. We want to use hard gold similar to gold used for edge fingers because our customer is concerned about wear and conductivity of connector

You may want to tack a coup[le of leads first, making sure that the component is fully seated against the PCBA. Or what we do is apply solder to the E-Pad and the lead pads and then hit it with a "heat gun" until the solder melts on the E-Pad and th

You might keep a eye on SMT auctions, Sometimes you can get a good deal. As long as you get the feeder for less than 100-200$ each at auction/ up to 500$ each for a dual lane, you can be assured that you can fix it to fully working if its broken

Hello, We use SJ50 serie AOIs. I made a program which watches the .dat file and if an algorithm changes then my program makes a log file from the parameters of the modification. I know some numbers are which parameters, but I don't know all. I write

Ed, You certainly are ready for some equipment. I noticed in your message that you mentioned cost three times. So it is a very big issue to you. What everything depends on is where you see your company going in the next few years. Do you want
