Electronics Forum | Thu Jan 10 17:20:25 EST 2002 | Matt Kehoe

Dont forget, if you dont want to print paste and deal with the challenges of placing components in wet paste, solid solder deposit can save you the cost of the stencil printer, while offering better first pass yields than traditional methods. It just

Typical SMT Machine changeover times?

Electronics Forum | Wed Mar 29 05:00:48 EST 2006 | rlackey

You could alternatively look at it another way - the customer asked how quick it would be to change over 20-25 feeders. All of the above machines have the capacity to hold at least double this, so the question is can you run the orignal product, w

Thermal Profiler Shield

Electronics Forum | Thu Jun 01 10:08:59 EDT 2006 | ratsalad

I sewed a sock out of a Nomex/Kevlar blend fabric because we had the same problem with our profiler. It works great. After one run through the reflow oven, the internal temp rises by about 5 degrees C. It used to go up by about 20-25 C. I can pic

Flux drop in lead free process

Electronics Forum | Mon Dec 18 04:11:11 EST 2006 | greg york

Probably because the flux manufacturers have deemed it necessary to increase flux volume by 20 - 25% compared to Leaded this is why more is being left over. Really not convinced of this increase in volume actually does anything. Black residue will be

The best buy you can do right now. There's a lot on the market at cheap price. Easy to find feeders & spare parts at good price. You can find a good machine for $20-25K Dont buy with FlexJet head unless your use to work with these heads. Complicated

I had to replace two Y-axis servo amplifiers on our GSM1 machine. I'm sitting on two faulty servos that I would like to have repaired. Let me know if you now place which specializes in repair of Servo Amplifiers Mod. No. 800-444 by Copley Controls.

Humidity & Temperature Range on SMT SHopfloor

Electronics Forum | Mon Aug 26 12:37:58 EDT 2013 | deanm

Your stencil printing process is probably the most critical process in SMT. The paste I'm using states the best environment is with a temperature of 20-25C and humidity of 35-60% RH. Your paste may vary. We've run down to 10-15% RH with no measurable

SMT LINE CHOICE

Sounds like you are sorted then. Always liked Fuji kit, had it in previous companies. I'd also take a look at the software tools they are bundling in before signing, unless you have Valor, Unicam, Aegis or similar already to handle the programs, opt
