Many OEMs, including myself and going big for APEX. This is the 1 venue that still brings qualified people to technology. In tough times we find that small investments in technology and processes can make a huge difference in productivity. Vegas ha

Hi, in the beggining of PB free process, there were a lot of solder pastes based on a Bismuth and some other materials, mainly because of their low melting temperature. The feedback shows problems in the mechanical strenght of the joints with the ti

Hi, Is there any PTH Assembly after reflow, we found cracked joints on some BGAs which was caused by operators ing Oupin connectors which were a tight fit. This caused the PCB to flex hence cracking joints. One way of checking for this during test

I think so. My customer once assembled resistors 0402 ,by Glue+wave soldering process. But PCB must be printed soldermask bridge between 0402 SMD PADs, otherwise you would encounter short problem. Sorry I don't have any comment for recommended footp

Does anyone have design knowledge of why some manufacturers remove solder resist from the area around pads on fine pitch devices? What purpose does it serve? I only know that it would be better for AOI as you would not have light being reflected fro

Start off by suggesting that they buy the parts as they're going through their layout. Their engineers can output a BOM based on the design, and they ought to be able to buy to that. That also keeps you off the hook for material liability in case a

I totally agree with Wolfman. I recently had the SMA responsibility for a new product from a new customer. The PCB had 600+ mounting positions. It took me almost two days insering them into the part library because an unusual number of the positions
