| How about live scheduled chat via ICQ ( or other means)? Chat via ICQ may not be the best venue for more than a few users. We are looking into other means, including setting up a chat room on our site. We should have a prototype design within 2-3

Smart Sonic has a new Model 2003 Stencil Cleaner that is designed to clean SMD adhesives, solder paste and post solder flux residue from wave solder pallets, oven air amplifiers, etc. all in the same system at the same time with the same chemistry. C

Gold boards OK with SMT?

Electronics Forum | Thu Aug 06 12:58:35 EDT 1998 | Paul J. Lingane

Is there any problem using SMT on gold boards? 15 years ago we were told not to use gold boards, but I can't remember why. Judging by the other postings it now appears to be common. Only problem I see is that the nickel should be plated, not elect

200 boards an hour and probably does. Our slow P&P machine keeps us from getting that benefit. But we get to have all the headaches. I think the printer runs on a 286! That's pretty sorry for such an expensive piece of equipment. The stencil frame is

Wayne We (Universal Instruments) started demonstrating the placement of 0201 chips at the last Productronica show in Germany. But at this point in time, you will be hard pressed to find anyone using it in production (although the placement equipment

Re: Wave soldering of 0402 Chips.

Electronics Forum | Sat Jun 20 00:22:12 EDT 1998 | Arul vanan

Presently many of our boards are wave soldered with 0603 chips on the bottom side, with soldering PPM level of 500 PPM. Apart from dispensing the glue we do screen print the glue depending upon the product maturity. My question is, 1. Can we print t
