Working DFM SMT issues with respect to a client's artwork together with a heavily modified solder stencil, I was able to reduce 0402 tombstoning from 80% across the board to 3%. I winged the aperture reductions, but are there any "rules" or guidelin

Tried both, with no success. The big guys are pretty secretive about how they do things. The lawyer understands arbitration and things like that, but doesn't have a clue about customer furnished materials or volume pricing. I have found that IPC is w

We are investigating a system, using 2-D matrix code, that will identify and track every PCB throughout our factory, starting from bare board. As a low-medium volume manufacturer, would labels or laser marking be more cost-effective? How difficult is

Hi. I am trying to understand Tg and how it relates to reflow. With the higher temperatures of lead free, we have been looking toward laminates with a Tg of 180 instead of the current 140. My question is a little more general. In either lead free

Hey pr...sure it's warm there, but I also hear that in that area where you live it's not too uncommon to have a kiddie pool in the front yard (with a couple of darkies in there), pickup truck parked on the front lawn, chain-link dog jails, with you o

Steve, KIC does. The new KIC2000 has built in dwell time sensors. You can buy KIC's wavesurfer option (like MOLE's waverider), or you can engineer a custom pallet for 1/3 the price. I made a custom pallet and took advantage of the KIC's automatic

Mydata is a large footprint. I would personally look into AIM, XP242, or even universals or panasonics. I would make sure to watch auctions or check used market. We just purchased a XP242 not long ago from auction for about half the proce of a new on

We just placed a 56 pin QFN, 1 per board, on 10 boards and had zero defects. A good paste job, proper placement and a correct oven profile are the keys. If these are set up correctly, on larger runs your defects won't be zero but they should be le
