Well, you've got a lot of nice equipment for soldering/de-soldering. However for those not so well equipped, I strongly suggest removing any ICs (QFP, PLCC etc.. no BGA) using Chip Quick. I just tried this stuff and I am in shock!
This is so easy and cheap. I've removed hundreds of ICs in my life with all sorts of tools and sometimes I ripped the pads off or what have you.. and Chip Quick was just so unbelievably great.
I've always maintained that you have to consider all methods when you do rework or any other task and you have to accept technical changes that work or at least acknowledge them. I have also used Chip Quick and it is now a primary consideration for device removal. As for equipment, I enjoy collecting them provided they are inexpensive and functional. Thanks for your comment. :-)
@fireicer I generally like to keep the temps for preheating at approximately 150-175 C as this actually allows me to keep the hot air wand temp much lower to reduce damages such as "popcorning". Keeping rework temps below 350 C is becoming more popular to reduce failures in PCB's even though they passed the initial repair confidence tests.
@pozzo1979 Absolutely...most techs use several different methods to desolder. It's a matter of application need and comfort. The thing to remember is that while the component is dead, your PCB is still vulnerable. So picking the right method is resultant of past experience. Like all other techs...just an opinion.
It's a preheater for using a hot air system. It preheats a larger area slowly to reduce thermal shock when applying focused high heat with the heat wand. Not all techs use this method, but I leave nothing to chance with hard to acquire expensive boards. Personal choice. Thanks for watching the vid.
@bPaIsNtKaYrd Thermal shock can destroy just about any component, including but not limited to traces/pads on the PCB. Semiconductors internally and/or externally can be ruined in mechanical terms. Too much heat will destroy the semiconductors in a different way, thermal decomposition of the P-N materials. Hope this helps.
@rkruetzfeldt yes its helpfull coz of today i have destroyed 2 ics one was useless for me (la71750) i thinking of it is vid and musq driver for whs player as i have said useless for me and PT6955 (7X4 segment display contr.) this ic miss me from cause of i need it for my project . the preheater is useful machine but i thinking of that today my 2ics destroyed a lot of heat (290° for 20sec(hot air gun) from cause of fucking heat resistible glue) . i have to buy desolderin´ unit or sth similar
Usually there are no problems. There is a limited window of time to perform this type of procedure. The newer chips are more resilient concerning heat exposure than older units, Practice on old or dead chips to get your time to replace chips dialed in before you jump into it with new chips.
@hannobisschoff1 It took about 5-6 yrs, because I shopped for good deals on e-bay and locally and I was slightly picky. Patience pays well and I have a reaped its rewards. The best advice I can give you is figure out what you want your shop to do and plan for flexibility and veersatility. I plan on doing a tour of my shop as soon as I clean it up a little or alot.
Thanks....believe it or not, the workshop is getting remodeled next summer. Trying to streamline it so I can introduce SMT/SMD production into my shop.
@noninfinitum, I've tried to track it down but have had no success. If you know of a way to reveal its I.D., I will be more than happy to find the artist/title. RK
Whay is every SMD rework vid accompanied by music, and not commentary...perhaps everyone who does this has no voice becasue they have breathed in too many flux fumes?

And no.. I don't work for the company ;)

how did you find out that this chip was casue of problems?

What temperature generally do you preheat the pcb board to if you dont mind me asking. It looked like you were up in the 200c.

Wow, that's a really nice setup!
Just a question: would something like ChipQuik paste allow you to desolder the chip without needing a hot air gun??
I need to desolder a PLCC32 chip from my laptop's mainboard because of a bad bios flash, but I don't have hot air guns :(

Hi, I can't help but be a little jealous of your lab/workspace. How long did It take you to build up such an array of gear?
