To answer Gary's question: Gary, you will need a production board, thermal profiler, flux vendors product data sheet on the flux you intend to use, maybe your wave vendor service engineer or wave solder vendor contact (unless you know your wave) and

Hi We are trying to Solder LCD Flex to PCB. Few suggested Z-Axis Film (Conductive tape) which can be stuck between Flex-PCB and bonding by applying hot soldering iron across the flex. Is this effective method. If there is any other option, please su

Hi, One other note. You don't want gold to be more than 1% to 2% of the the solder joint. Above this percentage you will have embrittlemant issues. Lots of information on gold embrittlement on this site and on the Internet. I estimate your produ

We agree with Chunks. You need to turn-up the heat [slow the conveyor] because you have significantly changed the melting point of the solder alloy by adding so much gold. Relative to ENIG you should expect: * Similarly smooth surface, possibly a l

John: As one of the previous replies indicated a LASER of the proper wavelength (organic materials) will do this job. Contact BEST at http://www.solder.net offline to see if this is an option you want to pursue. Other methods include labels and m

Hi Chuck, let�s say it the other way round. We use noclean since I can�t even remember without nitrogen and all of our subcons do with no known problems. The processes are adapted to it and no complaints are heard up to now. That is related to our pr

I am looking for white papers or information on what happens to 63/37 solder paste alloys when overheated. I have had some solder joint analysis done regarding missing finish on some of the joints. The analysis came back showing a low lead content

We are trying to apply solder to boards with 80 microinches of electro plated hard gold. No components involved, just print 63/37 paste and reflow. The results are very poor on some boards, not so bad on others? Pictures at http://www.sipad.net/thick

We're currently experiencing a spate of solder not wetting to pads of PCBs, and it's becoming more aggravating on a daily basis. At this point, we're running out of ideas. I've searched the Fine Archives for information, and, so far, haven't found

What is the purpose of glueing it? If it is glue the bottom side parts followed by reflowing the top side parts followed by wave soldering the bottom side parts, then it's easy to measure. Hold the board with the 0603s facing down. If they don't f
