Using a flux pen sounds like a good idea. Comments are: * I assume you�re talking aqueous flux. If not, some NC flux pens leave white residues. Nearly all of 15 samples suffered to varying degrees with white residues. * Use the same flux that you

We think all you need to do is explain: * Which portion of the 60 gallons of water contains the hazmat * How you seperate and contain that portion from the non-contaminated portion when your washer leaks We'd go for a waiver

We're dealing with upcoming (Oct. 2008) requirements for secondary containment of hazardous material that are dependant upon volume. 20 gallons or 200 lbs. (dry). Our washer has a 60 gallon wash sump and a 35 gallon rinse sump. The challeng is how

Suppliers list the contents of their products in a MSDS. Libraries of these sheets are listed online. Look up the product you're using there. A safety data sheet, material safety data sheet, or product safety data sheet is a document that lists info

We use 4140 steel (same as a lot of other OEM's). The user will need to pre-flux and tin before installing in the machine.

I got an inquiry from one of our electronics labs with regards to their soldering processes. They use eutectic (63% Sn, 37% Pb) solder. For liquid flux they are currently using Kester 186, which is an old-school, full rosin (RMA and ROL1) flux that c

| I am about to embark on an effort to evaluate 3 different solder material suppliers and their recommended materials for our assembly process, in an effort to find the best supplier/material. We do mixed technology, with NOCLEAN chemistry so I will
