Shows how to safely remove an SMD IC using just a good iron and some solder. If done properly, there is no damage to the board or IC, and both can be re used. No force is applied to the PCB.
This example is a fine pitch TSSOP with 20mils (0.020″) pitch, one of the densest ones.
Procedure as follows:
1. Set your iron at about 340-360 degrees C maximum. You will need a good powerful iron, one with a lot of wattage (40..80W) but controlled temperature. There is never any need to use higher temperatures than 360C. But your 10W iron may not be powerful enough.
2. Apply a lot of solder beads on the pins. You need to create a big solder mass so that it preserves the heat and won’t cool very fast.
3. When you have put a lot of solder beads on both sides of the IC, start the heating procedure. The aim is to heat both sides and have molten solder on both sides simultaneously. Keep bouncing the iron from side to side, and when the solder is hot enough, circle it around the package.
4. Soon the solder melts at both sides, the pins will be freed and the ic can be gently pushed out of the footprint.

American Standard Circuits to Exhibit at Montreal/Pointe-Claire and Markham EPTECH Exhibitions
American Standard Circuits has stated that it will be exhibiting this year at both the Montreal/Pointe-Claire and Markham EPTECH (Electronics Products and Technology) shows.
The Montreal/Pointe-Claire show is going to be hosted on Apr 25th from 10:00 AM to 4:00 PM at the Holiday Inn & Suites in Pointe-Claire. The Markham show will be hosted 2 days later on Apr 27th from 10:00 AM to 4:00 PM at Le Parc in Thornhill, Ontario.
“As this year’s trade exhibition circuit begins, we’re very happy to let everyone know about all of the brand new products and technologies we have to discuss. During the past year, we’ve devoted a substantial amount of time and expense on strengthening our factory in West Chicago and exhibiting at events, for example, the EPTECH shows, offers us the chance to talk with our buyers nose to nose about these improvements. This year we’re primarily excited about speaking with these companies concerning our new downloadable micro eBook, The Circuit Board Designer’s Help guide to Flex and Rigid-Flex Fundamentals,” said American Standard Circuits CEO, Anaya Vardya.
