I would be concerned with either material at that temp. i would re-post your question on one of the engineering forums below. http://www.eng-tips.com/ http://www.electronic-circuits-diagrams.com/forum/ Regards, Boardhouse

Hi, We have a PCB with layers defined for a thickness of 1.6mm from a customer . Is it possible to make it 2mm without affecting any Cu traces or layers , just by altering the FR4 material only.

Normally someone would have replied to tell you to do a search of the archives. I've read at least 4 or 5 different threads dealing with baking out PWB's, but none were for this special material. First, have you contacted the manufacturer of the PW

Durastone is commonly used in flooring. Durostone is a proprietary product of R�chling Permali Composites SA [be aware this is a French company] that many use for reflow and SMT process pallets. Suppliers are: * R�chling Permali Composites SA; Canog

| Problem occurs because the glass transition temp for FR4 is lower than reflow temperature. Our company wrote an article which was printed in SMT magazine some years ago | that deals with this exact subject. Best way to deal with this is to use a ce

Does anybody know what material is used for over molding I/Cs. I would like to find a material that others use to mold there electronic components. I am wire bonding and mounting a small cap (0201) on an FR-4 board. I need this material to withsta

No one knows what type of board you use. So, assuming you're talking a fairly standard FR4. Q1a. actually, what is max temperature and duration can a bare PCB reflow without any quality problem? A1a. We'd guess your board could take 250*C for may

| I am looking for a rule of thumb regarding the maximum ramp standard components (chip capacitors) can tolerate without failure during the reflow process. The standard seems to be 3C\second, but this figure is generally derived from the average ram

My question is concerning a cheap PCB material. I have a sample with me and I have to quote on this product with the same PCB material. This material is not FR4 and the color is beige. I think CEM-1 material is beige too but I`m not sure. I`ve hea
