From Indium Guru, (Hi Rich). "Ramp can be taken anywhere.... but mainly you want to look at the ramp when the flux is doing it's job. For the Indium paste, I would set a ramp rate of 100 to 200 (or 120 to 210).. somewhwere in that range should provi

I wouldn't expect them to define squeegee speeds any more than they would tell me which printer, squeegee blade, or surface metallization to use. Start at 1"/sec. and see what it looks like. Try 2"/sec and .5"/sec. and see if they're any worse or b

that crossed our minds - overloading of the oven but in reality we produce 5 references with very little output difference (close to 2 sec difference) so it should be a problem since a few yeats and on all references...? no only on 2 references from

We are looking at a third P&P machine for our factory. I have received brochures on a SMASUNG CP30V machine. It looks great and has all the plus points for a contract manufacturing company such as ourselves. The basic specs are: 14400 cph - 3 heads

1/8" cutters, although they can only be used with our newer height-controlled machines. 3. Reduction of operating parameters. Reduced Z-axis plunge rates for the larger cutter sizes. 4. Addition of a 1/2 sec. dwell at the plunges. The small pause he

Hi all, been recently wave soldering some pcbs with no problems and have now noticed what looks like blue residues on some solder joints. We have been running this product for around six months and this is the first time we have seen this. It is rand

The machine does not have pre-heating feature. I'm soldering a six-up panel...I've tried putting them a an oven and letting them soak for 20 mins or so at a low temp. But by the time I placed the panel in the machine and manually fluxed the top sid

I attended SMTA's copper dissolution webinar this morning and am almost convinced that this is not our problem. Still planning to do cross sections to verify but our dwell times are nowhere near levels that could cause a problem assuming good platin

A solder wetting balance will indicate a time of less than one second for wetting to occur to a solderable surface. The additional time is required to get the metalized surfaces up to soldering temperature. A single sided board has very little mass a
