Hi CW, Regarding orientation, yes, your diagram is right - see the following link for confirmation. http://search.murata.co.jp/Ceramy/image/img/A18X/C2EB3C.PDF Regarding information on bending strength you want to talk to your local Murata office

Hi CW, Larger chip caps can be susceptable to cracking, but mainly this is due to handling - flexing of boards is the main culprit (the part being mechanically joined at both ends to the board). PCB's usually flex easiest along one axis, and larger

hi Bob, Thanks for the info. I understand your comments, but I am looking for specific guidance, If I am putting chip capacitors on a .063 FR4 board, what size package should we stay away from to avoid cracking? (I realize this is dependent on h

I've been approached by my design engineer who would like to know what is the largest component I can place on the secondary side of a double-sided PCB (without adhesive or glue) and not have it fall off when I run the top side. Currently, I can plac

For your responce on OrbelE-Z SHIELD. Are you referenceing the PCB pad is 1 to 1 with the fence foot print? Thanks

the only components I have had trouble with so far are PLCC68 and larger, Large Coils (2b and 3b size) Heavy crystals. Some BGAs if they are not PBGAs. There was a discussion on this and a formula was given to determine if a part will hang under th

It matters on how you setup your oven profile. I have placed J-leads on both sides with no problems. Also, have come across some fine pitch but wouldnt suggest this too often. Give some examples that he would like to see placed on the bottom side of

That's thin board. The test that you ran is the best method for determining the specific answer. Bob Willis says, "Use pad mating to lead wetting area. Some have found the ratio to be as much as 44 grams/sq in." Bob Willis and Phil Zarrow have po
