Consider that printing may not be the only approach to getting paste on to your board. Would a dispenser work better?

Thanks Rob. I'm not so sure in a mass production environment that using the mount spray and kapton tapes are going to be efficient. For solder paste dispensing, any idea what is the smallest solder dot size the machine can dispense?

I just assume when you have laminates that thin, it will invariably be warped in some degree. I have worked on a few and I have never seen one that is not warped consistently.

Looks like a similar product to magic resin. Thanks I'll check it out.

Hi Rob, So do you have to constantly remove the old adhesive and spray on new ones? Is that an automated process? Also for the kapton tape removal and application, is that automated as well?

Dispensing: You can dispense for 0201 and above Warped laminates: Ask your laminate fabricator what's ausing the warping and how to make it go away

I have a few LED pcb's that have an aluminum substrate that are ridiculous to rework. They heat-sink like crazy and I can't reflow the bad LED's, no matter how much heat I apply. Any suggestions on techniques or equipment to use?

We are having an issue w/PCB stretch & shrinkage over some 300mm panels. 5-up array, w/the smallest pads at 6mil (QFN). Is anyone aware of a machine that will measure the distance between features on the substrates? Tony

Looks like a screen printed circuit using a platinum or palladium silver paste. This would account for the grainy appearance. I 've seen this on a white ceramic substrate but not on aluminum. Any components are attached using a silver conductive epox

From the poor bonding strength of the board, the surface quality problems of the board are divided into: 1. The cleanliness of the board surface; 2. The problem of micro graphite (or surface energy) on the surface. PCB circuit board proofing Youke bo
