I've had this problem before. Typically happens when the Lithium Battery dies and the machine loses the program. Usually you can pull the displays out and ship them to Simplematic. They can reload the program for you. Roughly $2500 bucks I think. Cal

| first of all what is the technical term for the small amount of solder on a plated pad. we are getting poor screen printing gasketing on a 20 mil qfp due to this solder not being even or too high in spots and not covering the length of the pads. an

I wonder what kind of equipment the board designer had in mind? Are you shure you can do the board with a Mydata ? Where do you put the tray for your 20 mil QFP's? 10 mm thick plus component height also appears to be a problem. Multitroniks can do la

Basically the same exact way as a much smaller board. The only difference is the profile. Most of our boards are 0.063" thick. Looks like you found your problem. If the edges of the board are cold relative to the rework site (high difference in t

We use same methods of PCB attachment to carrier as Rob lists. To be more specific on pocket size, we machine our durostone carriers so there is 0.010 inch gap around perimeter of board. This might seem like a lot but (from my experience) you will

We are having some issues with a RF PCB aprox 1" x 1". The pads are in the bottom of the PCB and it goes on the Top side of the mother board the pads of the RF board are like a BGA (square pads)and we have troubles to make the proper welding in the

We will be running a very large board with 62k+ components on it in the coming week. Has anyone run boards with this qty before? For sanity sake I had to split up the board into 12 individual programs. We will be forced to run it on a My12 due to

How are people getting BGAs reworked on boards that are 15"x15" at .06" thick? The BGAs are pretty much in the center of these assemblies. We have just received these and I cannot keep from warping/bowing as much as 1/2" at the heated area. Our bot

We just got a contract to build a board with 1400+ SMT placements. This thing is 16" x 12" and the PCB thickness is 0.142". Dead center is a 580+ pin BGA that costs about $600. I'm a bit intimidated... I've done lots of mole profiling on BGA's bu
