Check the dimensions of the components in question with a caliper and put the correct numbers in Your part data. Check that the correct nozzle is being used. Also make sure that you have the right pcb height in Your program. This is somewhat criti

| For space contracts we have to mount chip capacitors/ resistors etc 0.1 to 0.4 mm from the pad height. | | This is to compenstae for the CTE differential in the substrate/component and also to ensure cleanliness. | | Does anyone have any new idea

I hate to sound like a broken record but the industry has been placing lead free through-hole parts forever. Now all of a sudden its a problem??? Gold finish, silver, silver paladium, alloy 42, even pure copper. Reliability will be a function of t

| Does anyone know why this typically occurs. We have seen capacitors crack due to stressing. Any good solutions? | Regards, | | Steve. Hi steve! Did you check component date-code, reflow profile and component placement height. it has happen to me

One more variable I've remembered - pad height with respect to solder mask height. Pads being too low can cause stencil "gasketing" problems that in turn allow more paste to be deposited than needed. Are your fabs HASL or some other media?

If your part height(thickness) is set too tall in the software, the machine will drop the component before it touches the paste. If your part height(thickness) is set too short in the software you will smash the part into the paste. This can cause da

I am not sure about 643's, but on a 642 machine, the pickup height @ station 1 is critical. Especially on 0402's. The should be a spec, and instruction on how to verify in your maint. manual. Bad pickup height can cause you all kinds of headaches on

Did you ask Mirtec? When we were ready to buy a Mirtec they asked if we needed more than normal clearance height. I do not know if this would be retrofitable but maybe you could ask. Jerry

Your Mydata should have come with a myriad of preprogrammed packages, specifying height (ex. 0805-05, 0805 components with height of 0.5mm).
