Hi Anthony! Earl's right, things can get rather involved when you start discussing ALL the things that affect whether or not a board is going to warp. The way I look at the issue is try to separate the warp issue into two catagories; 1. The board bei

| We are in the process of deciding whether to change a PCB product from a single board to a 3 up panel array. Could you please advise on the most effective removal design, either scoring or snap off, taking into account that material utilisation is

Hi! I'm looking to find a training course for PCB design & layout. It would be prefer to be in Canada, if such courses are available here... if not I'll go where ever I have to. The course should be about the following points or more: -Crosstalk -cou

Hi Guys, (Note: We are not talking about bill-board RES/CAP, we are talking about Z-axis slant/tilted RES/CAP with respect to the PCB pad Z-axis plane). 1) We ref through the IPC-A-610C specification "bible", and can not find a "chapter/verse" tha

After a whole night's self review, I think we can term the slant/tilt as "floating 0805, yet end-terminals have acceptable solder joint formation". the width portion of the 0805 RES/CAP is (floating)elevated from the PCB pad, yet both (width) termin

Hi Guys, I have a fine pitch QFP that I suspect of having a solderability (wetability) problem. The heel joint is 50%-75% of the lead thickness so it means that I passed the IPC Class 2 recommended criteria on the Heel. The toe has at least 25%-50% s
