Hi there. We are facing an issue with the placing head of our SMT machine SIEMENS SIPLACE CF 2004 model where the vacuum reading is low (820 instead of 900). This is resulting in that the components are either falling off when the head moves onto the

Solder paste flux is main contributor, Lead termination chemical-oxide by products and PCB Plating-Chemicals. Reflow profile would have very limited if not no impact really unless is way off. Paste volume control and Stencil design plays a big part

There is a quick change dedicated tooling solution. It involves a "h-tower" and a machined vacuum (or non-vacuum) plate. There are two 8mm threaded holes on the table that are there for support tooling interface. The tower or tooling bolts to thos

Do you still have the vacuum plates in? If so, you can set the grid-lok up in the "fixed mode" (not sure what they call it,where it won't set for each board), then you could run without side clamps and the Vacuum should be enough to keep it from movi

This machines support table looks similar to AP and UP machines. I believe MPM published the dimensions of the "H" tower that the dedicated plates bolts to. As far as the plate, they are typically (2) pieces with the inside hollowed out to allow for

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

| Question for you SMT guru's out there. | | What is the best way to support boards on Fuji's CP6 machine's x-y table...particularly for 2nd side SMT where the support side already has parts... I am toying around with the following methods: | | 1.

Dedicated tooling uses what MPM calls an "H" tower. You mount the board support plate (dedicated tooling) on top of the H tower. If boards are only single-sided SMT, meaning only components on one side, the board support plate is flat with vacuum hol

Ok guys, I need help. Here's the deal. We're getting micro solder balls under discreets on the bottomside of the board. Here's my set up... MPM screener w/vacuum plate 6 mil metal screen with 90% circular (rounded) apertures 7 mil (measured) past

About the automated printing machines: They are all a little different, but the alignment part of the process is basically the same. I don't know if you have ever seen an automatic printer, so I'll do my best to explain it. The PCB rides into the
