In response to your questions: * Will a polyurethane squeegee blade help? NO * Will a Pro-Flow head help? NO, but it might be a cool excuse to buy one. Unfortunately, you will look like a jerk, if you talk your boss into buying one and then he /

Eric: I�ll pass on the uV and ammonia, also. Thoughts are: 1 You�re correct that the temperature/humidity mix can be a big driver to latex peelable solder mask cure time, but don�t overlook material thickness. Dispensers put material in a very th

Scott: First, it's neat that you do cartridge monitoring on you staff. We do that once a year. We (and I assume others) are responding to OSHA requirements: Lead CFR 1910.1025 permissible exposure limits for lead, provisions for medical examinati

Well as you have probably already noticed we relaunched our website this past weekend. It was a lot of work and took a little while but its finally here. That doesn't mean that we're "done" by any stretch of the imagination though. Most of the sit
