Not really. Our process is a solid solder deposition application so we are not placing components into the wet paste prior to reflow. We print the paste then reflow is without components, trying to create a meniscus which is then washed, flattened,

Some GD saleman [Oops, make that very nice saleman. He took me along for lunch.][Just kidding, all you sales types out there. You know how much I like to put burrs under your saddles. ;-) We kid because we care.] got into the catacombs to wake-up o

I would definately try to sell the bosses on the Grid-lok over the gel piggies. We evaluated both and wound up buying the Gel (for close to the same money). On an MPM if you put enough gel packs in the vacuum box (to support the board) it holds the b

D.B., You are justified in your concern over the last requirement. I have been imposed by a customer with the same hand solder/rework requirements. It seems the biggest concern is thermally shocking ceramic chips. You are much less likely to do this

Hello We have been working on the MPM's for over 11 years now. And we have never had any trouble with that circuit, just goes to show you. If you have one of the old, old manuals you will find a lot of errors. They corrected them as they went. We

Pros are no need to clean after reflow. No need to buy a cleaner or worry about "wet" parts afterwards when you're trying to test your unit. Cons are that most leave a bit of a residue behind. It's harmless but may drive your bed-of-nails tester a

Hi Serge, If you are really looking at a new machine, why not try Assembleon AX-3 configured for 45K cph (rated speed, 30K IPC9850 speed). This machine can be future upgraded upto 90K cph (rated speed, 60Kcph IPC 9850 speed). You get placement force

First, we know nothing about your assemblies or how storing them in an "unconditioned" warehouse will affect their performance or post-storage processing. Second, there are no specifications, because what might be good in one application might not b

We are attempting to increase utilization of our Pick and Place equipment (MY9) by transfering more components into the SMT area. Large gains could be had if we can successfully place a metal socket with a lipped pickup surface into a circuit board h
