Heat guns used improperly will definitely damage components. You must have a controlled heat gun that can be set to the max temp you want pb =215C max, Pbfree maybe 240C max. This heat gun must not be able to be adjusted or you must have total trus

If your component meets ANSI/J-STD-002 - Solderability Tests for Component Leads, Terminations, Lugs, Terminals, and Wires, then the problem is at your customer's operation. If the problem is at your customer's operation, it's very difficult to anal

Russ, We use a unit called a Datapaq surveyor to monitor our ovens. Its basically a unit that a data logger rides through the oven in. It has 3 thermal couples across the top and 3 across the bottom. It takes measurements the full width of the proces

According to the original article, no. It is formed by the FR4 expanding and then contracting. So cooling it down faster would not help - in theory. We have not gone lead free yet, so take the above with a grain of WML. My question to those that

As mentioned, there are many ways to achieve a quick changeover. Every manufacturing environment is somewhat different..but here's a few ideas for you to consider 1. If you have lots of feeder space on a machine you can have several simultaneous se

Thanks for the replies.With which ever machine we decide on the feeders with the most commonly used parts will stay on the machine. Also parts used on other jobs but not needed for the current one will be able to stay as well. The problem well run in

Since you are a HM/LV facility take a look at the feeder design. I noticed that the MyData feeders (that I have seen) peel back a lot of pockets before the pick, so when you change part numbers on the feeder there is a larger waste of components. O
