Are you using HASL PCB's? Try measuring a bare board and compare.

Hi, check the Land pattern 0201 on the board, compare with another 0201. Could be different gap.,

The right way will be to use CAD for programming and then compare to BOM.

Thank you! Omron seems good and its not that expensive if you compare it to koh young etc.

Does this device have a integral heat sink / metal slug on top, like a TI TM320C6XXX er a Altera EP20K4XX? Compare the size of the pads on the interposer and the board. Compare the type solder mask [NSMD vs SMD] on the interposer and the board. Wh

DEAR ALL WE ARE LOOKING FOR A DIGITAL VIDEO COMPARATOR ,AN INSPECTION TOOL WHICH WILL HELP ME TO LOOK FOR ,MISSING COMPONENTS,VALUE,DIRCTION ETC, AND IT SHOULD BE ABLE TO BE PROGRAMMED BY PLACING A GOOD BOARD. IT SHOULD ACT MORE LIKE AN AUTOMATIC OP

Are there any equipment manufacturers that provide this option? I have a potential customer who has stated the other CM's he has looked at has this option on their equipment. I have never heard of an optical comparator built into a pick and place mac

Mika, If I understand you correctly you compare hole fill of Ni/Au plated boards in a lead-free process with HASL 63/37 boards soldered with leaded solder. If this is the case you might be facing the challenges in Pb free wave soldering with the lim

This make me curious how many people are using sn100 versus how many using sac305. The sn100 seemed to generally cover the pads and flow a little better, and looked nicer, but SAC305 overall was easier. Is this normal or do I need to work more on sa

We use succesfully SN100C on ERSA330 for about 2-3years. Pros: - price, - less dross comparing to SAC305, - some ppl say better mechanical durability comparing to SAC305 (depends who pay for "independent" studies) Cons: - higher melting temp so r
