I think Sr is right. Miss prints are prolly a result of your tooling moving the board after the camera looks at the fids. It also could be the camera itself hitting the board from warpped board or tooling raising the board up. It may be the camera

me and my big mouth. we are currently running a leadfree product and I am getting MCSB on all 1210 caps. Using homeplate with 10% reduction 6thou stencil. I contacted my stencil supplier to ask for advice- they are looking into it but he did menti

We have solved our MCSB problems by using standard homeplate designs on all of our resistors and caps. I use a 50% taper and have achieved great results with 0402-1206 parts using both tin/lead and SAC305 paste. We use Amtech paste.

Hi, Maybe I am a little bit slow, but please explain exactly what is your point here? The RoHs directive is wrong, or what? So You slam the door on the RoHs directive, just because You don't get the whole picture or perhaps You do?

John, Your calculation looks fine. If that's all you were looking for your done. If you really want to produce more boards per day we would need more info. Size of board, can it be panelized or larger panel. Your line configuration and what mac

IP? With a MY machine what is it you are tring to solve with an IP. If you are looking for a speed improvement and corresponding throughput the cost of running and maintaining an IP is not going to balance out. However putting a real chipshooter in f

If you are looking for an IP (defined as IC placer), and you liked the GSM1 with the worlds most hidious software, then look at the newer Universal Platforms - very good machines & they've sorted the software. Fuji Chipshooters & Maintenance? the IP

I understand that most PCB Repair kits do not contain lead. (Being "RoHS Compliant" and being "Lead-Free" are two seperate things.) I'm just looking for a kit that has been deemed "RoHS Compliant" by the manufacturer, and labeled as such to show "Due

All, We have a board that has failed at burn in. There is a 672 BGA on the board. When the test guy presses down on the BGA the board will pass ! What am I looking at here? Board finish is ENIG - could this be black pad / what should I do to diagn

could be black pad, or it is just bad reflow profile that did not get all balls soldered down. OR it could be a planarity issue between BGA and fab during assembly. Can we assume that this is proven design? Somewtimes in new design touching a BGA
