Sounds like you received some good advice. Most of our stencils are used once a day [at most], so more often than not they are air dried. If we goof-up and need to reuse a stencil during a day when we have limited drying capacity, we wipe the lowes

I have read that with the advent of no clean fluxes, Isopropyl alcohol is not the best cleaning agent to use when cleaning screen's and pcb's.Is this true?..and if so what are the alternatives ?. We have just changed 90% of our products over to NO CL

I recommend that you checkout the OnBoard Forum on Stencil Cleaning. You have to enter it via the SMTnet Home Page. I tried going through the OnBoard Forum link and could not see the data. Must be a software glitch. However, there is more informatio

Could anyone please give me some insight on the time/temperature requirements for curing SMT adhesive used for a high temperature (96/4 solder) application in a bake oven, rather than using reflow? I understand that it would probably vary from epoxy

You're right, manufacturers time/temps will vary. A single manufacturer will have a host of materials with different cure schedules. We currently use 2 epoxies that cure in 2 - 3 minutes at 150�C. One will also cure in 5 minutes at 125�C. Talk t

We don't do this, but if we had to and lacking better advice, for all components I�d dry pack according to J-STD-033, store in a low temperature and humidity controlled environment [maybe using some semicon fab inert storage cabinets], review the eff

Wow! It really works. I used Sprite instead of the hussle of melting suger. I did not use Coke as it leave behind a black stain. Now, I need to convince the facility people it will not attract ants. Or maybe it will be process inherant that ants wil

Ok I could not pass this one up so I tried it out today, it didn�t work for me. Could I get more information such as flux type, and sugar concentration? I used Kester RMA 285 and concentration almost to saturation (looked almost like syrup). I wander

I am a new user of an old PERMAX VMP-1000. The machine is in excellent condition but I do not have the software to link the machine with a PC. However I can program it from the machine keyboard but it would be very useful to do that from my comput
