Tom: You are right. Pre-heating is just as necessary in rework as it is in intiial production. Zephyrtronics produces an economical convective bottom side pre-heater known as an airbath. This product ramps the substrate and assembly at 2-4 degrees

Hi, I've measured a rework profile on a summit 750. my nearby parts are heating up as high as 178 to 182 degrees C. I'm concerned that this fine pitch parts that are nearby are affected specially their solder joints going to close to melting point.

I would say it depends on the process requirements for the board and the reliability requirements as has already been mentioned. If you do two-sided reflow you might allow for fewer rework attempts, for example. If it's a medical device you might on

I use a Liberty Bandit brand hot air rework station and have placed 676 ball BGA's with very few problems. All of our products are now RoHs. They have good product support and easy to use directions. I think this unit runs about 15,000 or so. Good lu

With regards to the rework, size and mass of the PCBs is important, in addition to the size of the components that are to be reworked. You might be in the game with $6K (APE Chipmaster Hot Air machine with Preheater or similar setup) if you have sma

It depends on what type of packages you will be working with. Will you be working with BGA/LGA devices or QFP. For QFP, Pace is a really good system. I would recommend a power supply with 3 ports: iron, de-solder, and hot air. You can replace mos

I have worked with the PDR type rework station on and off for 12 years and have found that the IR can offer a lot of advantages over hot air. As was mentioned the lack of nozzels is a great advantage. The back heater takes a while to warm up but on
