Pete: That ACL Staticide� is used on the bulb of the Arach Technology & Application Corp Vacuum Pen� to attain ESD proprties, make us uneasy. "Staticide" is a topical anti-static solution. It's a soap that absorbs moisture from the air to improve

I cannot report having experience with 0201 printing applications on flex circuits. Generally, I would be concerned with handling of the flex substrate. A carefully designed vacuum capable custom tooling fixture would likely be required to ensure p

1. Back in the early days of consumer digital cell phones, we ran into the same problem. PCB with 2000 parts in a 5"x2" area, and double sided. We ended up using our standard vacuum tooling for the NIC side and stiff ESD safe foam for the NAC side

"Poor release" (paste hanging-up in the stencil holes) could have three main (or combination of) causes: 1 Equipment * Proper aperture area ratio provide better release * Laser cut release better than chemical etched stencil 2 Process * Snap-off dis

A couple things on the Grid-Lok system. They now offer a top-side edge clamping system. The edge clamping system works very well for warped, twisted boards etc.. Using this system in the auto mode also allows the pins to contour to the geography of

You will need to prepare the component and site for rework. Using solder wick remove the solder from the pad site and the component balls. You can also use a heated Vacuum desoldering tool. To reball we have been using Winslow Automation reballing ki

When I was a younger man with a younger mans eyes it was easy to outplace a hand placement machine. Good hand eye co-ordination is all that is required now I would find it easier to use the machine , but my fine motor skills are still just as good. A

Slappy, Most of our discussions about flex came before the last great SMTnet.com server transition that destroyed the archives. Consider custom building carriers with tooling holes, vacuum line holes, alignment pins, multiple layers, etc. from uncl
