Se�or Tech: Would you believe it!!! We had the same thing about a week ago. The carbon layer is real thin, almost a brownish color, correct? Couldn�t figure it out for nuthin�. We were all just standing around like dupes, without a clue. We ende

I am currently looking at the volume of paste being deposited on a PWB 2.4mm thick with a 0.25mm tolerance. I am looking for information on PWB variation and a MPM AP25 series printer, and can the volume of paste be controlled on varing PWB thickness

AP25 can handle warped boards to a degree. I also depends on the board clamping system on the machine. There are three avbl. First is Universal Vacuum box, second is dedicated tooling with vacuum and third is Y Snugger tooling that does not use vacuu

We have been populating lot of BGA boards and for all these boards we have been using No clean solderpaste. We are under the impression that aqueous cleaning is not recommended for BGA boards as the residue cannot be cleaned properly. However we are

Abraham, it kinda depends on your BGA ball size, device height. The probem is that very few machines will manage to get cleanign fluid under a BGA and you certainly will struggle to get it dry. You would need to look at various supponofiers as well.

I got some information on this support mechanism but was a little unsure how it worked. Let's suppose you're getting ready to run the second side, do you place the board on this support and have the support travel into the printer? Or is the support

Guy,s I do not have Red-e-set, but Grid-lok offers a fully automatic system that easily installs onto the printers and P&P. It can be set to your board instantly by pressing one button or triggered by the printer to set for each consecutive PCB. They

Would like to know what people are doing to differentiate their lead and lead free environments in their production areas. How do you keep it separated? What, if any, visual colors do you use to indicate a lead free area? Gray? Green? For instance, w

The biggest fear is mixing the solder pastes and bar solder. Had a training program for teaching folks what the alloys are and how to read them. I have locked up the bar solder and use the buddy system to restock the pot. Put up many signs on le

Quad 4c's would be a great machine for what you are looking for. They are easy to learn for an smt machine and very reliable. Just realize that when you buy a machine that is no longer being improved...you can run into limitations. Those machines are
