hi, we just have a new board to mount and on it we have almost 15 connector like this one TSM-103-02-T-DH-LC...it's a SMT .025" (0,64MM) SQUARE POST HEADER we are not able to place this component with our machine( it's a philips) and doing it by

What is the height, width, and length of the connector, packaging? We currently place a 2x20 2mm gull wing SMT connector measuring 8mm H x 38mm L x 6.1mm W, packaged on tape and reel with a plastic pickup in the center. We do this on an Assembleon

Hi Guys, Anyone have "comments/testimony" on having possible quality level achievements, for AQL=0.1, C=0 ??? Is this a realistic "1st Pass Yield" expectation? how about for OQC submission Lots from production? especially in a high-mix, low-volu

I am looking technology for BCC package. The preliminary datasheet from customer show that it had rectangular flat pad on the joint. The smallest pitch is 0.6mm having 96 I/Os. I am currently putting BGA, uBGA, CSP and CBGA onto PCBs usinf no-clean

On our last thing like that [5X5, 32, er 28?], we printed bumps on the QFN, but you can't do that, so there's no sense in tormenting you. Ideas that come to mind are: * Search around SMTnet for a paper by Chrys Shea on controlling dispense shots as

Tom, I developed a process for applying solder bumps on BCC32 and BCC48 successfully on my previous employer. The quantities were in the thousands a week, the following process is what I was using: Insert BCC's on process carrier (carrier holds 500

Don't be concerned. Brian and Neil don't allow us to link directly to email from SMTnet [even though from the way the link changes color you'd think you could. They do this to subjugate the huddling masses and lord the power of cold fusion over us.

Nope, we do not have solder beads, like we said, what we have are near perfect solder fillets except for the portion where the component is "floating OFF" the pcb pads. We are now mucking through the IPC-A-610C for specifications dictation on "tilted

thanks for the opinion, dun think we want to drill the machine tables, due to SMT line config : 1) printer, 1unit machine 2) chip shooters, 3 units machine 3) IC mounter, 1 unit machine plus the potential void of machine warranty by the drilling,

hello evryone. I am rleatively new to smt production. Though we have been successfully running pcb assy's and getting very good solder quality we are trying to get some proccess control parameters set up for our printing process. We have a semiauto s
