Can you share some information on the hazardous materials and cleaning details for your manufacturing processes, please ? These are the questions I need to ask you: 1. Do you use brominated fire retardant in PWB material? If not, what other type

Cleaning of stencil

Electronics Forum | Thu Apr 22 10:43:25 EDT 2004 | tigerlordgm

We had a great deal of trouble cleaning adhesive residue from stencils using an alcohol stencil washer. Same kind of thing, adhesive build-up in aperture corners. The solution we came up with was to convert our stencil washer to run Zestron ES200, a

Reflow soldering of Solar panels

Only the manufacturer of this part can tell you if subjecting the entire assembly through reflow temps is okay. It is not a good assumption that "if a part can be hand soldered it can withstand reflow" there are many connectors/headers/buzzers/etc

solder iron tips

Electronics Forum | Mon Apr 26 17:05:36 EDT 2004 | babe

If you have deep pockets and wish to spend alot of money over the next few years, then yes, call Metcal. Whatever solder iron you plan to use, it is my suggestion that you take a look at the board that you are going to solder. How big are the pads? H

Let me pose this scenario and ask your opinion. My manufacturing plant is located in New Orleans. Since summer is close upon us, the humidity in my SMT room where the machines and components reside get around 30-50%RH. I've got this Siemens waffle ch

Recomendations? Fuji CP7 or Univ HSP4797?

Electronics Forum | Thu Mar 31 09:04:56 EST 2005 | gregf912

I agree with you on the service issue. Fuji service can be a little strange from the Japanese Service engineers and the Service department at Fuji America has been cut very lean. I have been involved with SMT production for 20 years from Automation E

The biggest fear is mixing the solder pastes and bar solder. Had a training program for teaching folks what the alloys are and how to read them. I have locked up the bar solder and use the buddy system to restock the pot. Put up many signs on le
