Why yes you do!!! Now you know if you make someone put RoHS compliant on their packaging that we will have to pay more for the same product right? hahaha I am not aware of anyone that has this published claim. Good Luck Russ

The different coefficient of expansion of materials used in some BGA can cause warping issues. We've talked about this previously on SMTnet. Search the fine SMTnet Archives. For instance: http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=2

Help us understand your question better by answering the following: * What is a 'used PCBA'? [Are these boards returned from a customer?] * What is on these boards that needs to be cleaned? * How clean do the boards need to be? How is this cleanline

Hi all All you wave soldering people, have you had any trouble in keeping the copper level of your SAC solder pots under control? How do you combat the gradual rise of copper contents owing to dissolution from through-hole component leads etc.?

Hi, We are using SACX and have not noticed any rise in copper. I do know that there are Solder Bars available without the Copper to try and bring the level under control. aj...

Steve, We use Heraeus PD 945 and clean with Electrolube SSS. It gives us a good result with both hand and ultrasonic cleaning. Also does a good job on solder paste.

AJ, I believe all of your questions are best answered by your pc board supplier. The answers will vary depending on pcb material, thickness, humidity level in your shop, etc. Too many variables to consider for a generic answer.

Hello, Have anyone of you any experience of mounting BGA-s on both side of the PCB in lead free process? Have you seen any problems after the second reflow? Is it something special to focus on? /Thomas
