Yes and Yes, Your solder supplier should recomend a profile (standard profile) in most cases you can follow it. Of course you should be running a thermal profile of each board type to verify it is within the specified temp rang. You should also chec

Does anyone have any information regarding damaged caused to components due to overheating primarily with a heatgun? I'm having a hard time getting engineering to comply. Thanks

We are currently experiencing problems with delamination during rework/2nd op activity on lead free. I am suspecting this is a result of the use of a heat gun to rework components. My assumption is that the high heat and time in area greatly increa

Ah, yes. The age-old battle of Production Supervision versus Process Engineering. I guess you just need to tell your Process Engineer, "Pretty please with sugar on top, investigate this f*cking issue."

RS sell a heat cun that is fully temperature adjustable buy one of them and pre set it to the right temp then put a calibration sticker over the control.

There is none, since we don't know your part or temp being used. A heat gun CAN be used to remove parts with no damage, if its controled. You need to look up your part on the manufacturers web site, find the process data (time/temp)the part is desi

You see? Chunks, here has the right idea! To the original poster, you need to show this post to your "Desk Jockey" Process Engineer. That's the problem with some Engineers today. They forget everything they learned in Engineering school, they get

Comp is relay. I've pulled the spec. Max 240. Using Leister h/g with manual temp settings from 1-6 (20 - 600C)set by the operator. Gun was set to setting 4. They are using the heat gun to reflow the solder after SMT but before wave. High fai
