First, let us pause for a moment, bow our heads, and say a small prayer for Ill. Second, the only thing that is absolutely necessary is to do some things that make your customer feel that you're smart and did a comprehensive job of assessing your ne

We have an outdated Metcal rework station and are thinking about purchasing a new one. We need something that has heat profile capability. We don't really need anything automated, just something that's affordable, durable, and gets the job done. Does

Operator, Think "opposite". You actually want to MINIMIZE the ramp-up rate. Think about 2 - 3�C per second as your upper limit for ramp up. You don't want to go more than 4�C per second for thermal shock reasons. All of this, of course, depends

The loaders/carriers work well on CP643's in my opinion. We have had ours for about 4 years. However, if you crash them it can be a beeoch to get everything back into proper function. We have very little issue as long as we have our techs do rail wi

Can you tell me what LED's you are wanting to use and what size panel you will be putting them on? What kind of parts per hour placement to you want. I have a very fast and accurate hot bar solder system that may meet your application. It maybe used

We too are trialling WS819 with SAC305 alloy. The foaming in cleaning causes us a headache but all other attributes seem much improved over earlier types. Previously we were using WS619 - no foaming issues but MUCH shorter stencil life (less than 4 h

Your IC's should run great. I have changed out a handful of cameras inside the box (you know when your camera is burning out because the monitor will show black/gray horizontal lines). It's pretty easy. Aftermarket cameras are about $350 I believe

Dave that's actually what I want to work on the next time we run these. Our issue with these right now is that weight distribution on the boards mandates that we break a 4-up panel into two pieces and run it 90 degrees to the ideal orientation (=s wh

Actually we don't have local fume extraction at our soldering stations. We have 4 going at a time. I was researching last night and found this website. http://www.engineeringtoolbox.com/air-change-rate-room-d_867.html It indicates 10-15 air changes p
