Try Hi-grade Alloy Corp in Chicago we sell the flux over in the Uk and have several companies using 3541 flux on the Versaflow, works really well no bridging or icicling

Hi, This is true if you are using the Grid-lok in the "full auto mode" which sets and resets for every pcb. Ohterwise you can teach the system a flat board (by various techniques) and it will maintain that profile throughout the product run. You sho

We have recently aquired an MPM SPM stencil printer with an under stencil wiper. I have a list of approved solvents from MPM, but before I go and buy one I thought I would see what the fine people of SMTnet are using for their wiper solvent needs.

I agree with dry wiping. We have 4 SPM's and 2 AP25's, we have never had a need for solvent. I would be cautious using alcohol/ or alcohol based solvents.

I have used MPM 3000 and Dek 265 Horizon. We always just fill them up with regular old alcohol. Cheapest and easiest way to maintain.

Jun, What is your RH in the SMT area? Is a different paste used on this product than on the other lines. Could your paste be absorbing humidity from the air and discharging the moisture at reflow? This will cuase what you are describing. Good Luck

Bobvsi: A couple of questions for you: * How does adding a low melting point solder to your "regular" [near eutectic] solder increase the speed of removing components? * How does what are the solder alloys that form when using this low temoerature so

From my experience, stencil thickness should be determined by your minimum component lead pitch and squeegee pressure will be determine by the type of squeegees you are using. Best method of checking whether or not your screen printer is set up and

We want to insert 4 legged LEDs (superflux LEDs)in the PCB. Please advise what kind of automation equipment can we use?
