Multiple reflow cycles

Electronics Forum | Thu Mar 13 19:11:03 EST 2003 | Wes

Does a third solder reflow compromise component and solder reliability? We find that the only way to rework a particular BGA without warpage is to reflow the entire board.

Hi, I can verify that, and we have done 2 or more reflows with prototypes, using vapor phase reflow, and because there is no oxygen, the result is good, and you cannot tell the difference between the first reflow, and the 3rd. We are getting a vap

Regarding nano coatings : Nano coatings are susceptible to wear during the printing process and cleaning processes. As they wear they flake off and can potentially contaminate your solder. There is not a lot of independent data available on this so k

Good morning everybody Our PCB's keep on getting stuck on their way from the Printer to the SPI. That happens like between every 20 to 30 minutes. We've checked the conveyor with, the cleaning cycle and also the transport acceleration speed but none

The CP-65E handles a wide range of board sizes, including large boards up to 508 x 457 mm or 20 x 18 inches. Handling consumer as well as industrial applications, this durable and highly efficient machine achieves a cycle time of 0.12 seconds/shot an

Thermal cycles of tin lead solder in the Wave

Electronics Forum | Tue Oct 04 11:42:07 EDT 2005 | Bob Leible

I was wondering if anyone has studied the effects of tin lead solder in the wave. If we leave the same solder in the solder pot, how many COMPLETE cool downs and start ups can the solder go through before it begins to break down? Please let me know

Thermal cycles of tin lead solder in the Wave

Electronics Forum | Tue Oct 04 12:49:59 EDT 2005 | patrickbruneel

The amount of times the tin/lead solder can be melted and solidified is unlimited and the heat cycles do not affect the solder characteristics. The only reason for changing the solder pot is when impurities are at or over the maximum levels.

maximum number of reflow cycles for rigid PCB?

Electronics Forum | Thu Mar 15 12:33:50 EDT 2007 | ck_the_flip

To do a profile at most companies, if you don't have a scrap board handy, you'll use the already-soldered board that's already been through ONE reflow cycle. You spend time attaching T/C's with the aluminum tape - after all, the prep-work is half th

does any one know if you must register a ViTech 5000 AOI machine

Electronics Forum | Wed Jun 15 07:47:28 EDT 2011 | edmaya33

Any input on this machine good or bad would be > help ful, thanks This is a Good machine. 5K AOI Perform machine is easy to program and had a built in inline defect viewer. Low false failure/call compare to other platform. Able to detect skew, bri

Selective soldering

Electronics Forum | Fri Jun 06 13:00:40 EDT 2008 | gdzuber

Hello, The answer to your question depends on your using a point-to-point system, or nozzles. Some companies might use 3mm as the nozzle wall width. There are many approaches to selective soldering, depending on your desired cycle time. I can g
