Larger tighter spaced balls will present a problem in sealing the vacuum cup. There will be more leakage in this case. It really depends upon the application. The BGA you mention should not be a major concern. The bigger problems are with bigger

Pretty much everything under the sun. For example if Company A wanted to hire Company B to build printed circuit cards designed by Company A; What type of T & C might Company B seek in their contract/agreement with Company A? The following things c

Unfortunately, smt machines are not like TH sequencers. But, that is in their favor. Multiple reels, multiple part types, many positions = very flexible. Offline setup is paramount to line utilization. Remember, you only make money when the machi

Well first off I wouldn't evaluate paste for a wave process. I would use solder bar instead. Flux - top side fillets and no shorting on the solder side, does it clean well after processing if using water soluble flux. How wide is the process win

In the last couple of weeks ive been working with a new mechanical design engineer, i knew things were going to be difficult when i caught him putting a trial through a reflow oven using loctight thread lock to hold a smd led in place. but today i ha

Hi, That's great, and I did not know this was possible, as I did not see that thread when I searched the archives. Do you know of any companies that take your board outline and will design a palette to hold it through the printing, smt loading and

Hello, I have just installed the demo version of GC-Powerplace. Could anyone here walk me through the process to generate pick and place file from gerbers? I don't have solderpaste layer. All I have got is signal layers (top/bottom), soldermask, sil

Some Customers normally don't share CAD data in order not to copy the design. What you can do is use the Pick and Place file then plot to the pcb paste/silkscreen layer of the gerber using software. Not sure if your universal machine can load a gerb

Hello everyone, A few days ago I design one special kind of PCB for testing accuracy of our Pick and Place machines. (for trimming, calibrating, NPI etc.) I am looking for adhesive spray, to apply it on PCB (at the moment I'm using double sided tape

As far as I can remember, these always arrived in flexible plastic trays. The trays we designed were made of Durastone. The parts were then transferred at a tape & reel facility from tray to tray every 1000x connectors. If these are high volume for
