Greetings Tried to search past threads without an answer. I have a resistor that just fits the between pads. Some of the resisitor were installed without the termnation sitting on the pad and are infact sitting on solder a good .020 to .025 above th

Russ, The caps are 0603 case size. I am not sure about the manufacturing details, as I work for the capacitor supplier. The manufacturing details are unclear at the moment, as the customer (South of the border) has not released such detailed inform

Just when you think you're getting somewhere... QA sent me a vendor response to our corrective action request. They stated that their normal process for this product includes an ultrasonic cleaning cycle of 20 MINUTES minimum. It might be 30, we'r

Recent cross-section analysis for a customer complaint revealed voiding in the solder fillet. In some cases, the remains of outgassing were also observed. During the failure analysis, we also observed failures where the solder fillet wicked on the

Thanks for the info, Here is a couple more questions (and you thought you were done) What size are these caps /res? how thick is your stencil? what type of oven are you using? what is the finish of the board? Anyway, it seems like (from a distance)t

Hello I hope this helps For a component with axial leaded - vertical The clearance of the component body or weld bead above the land is 1.00mm (0.039in) Component body must be perpendicular to the board The overall height does not exceed maxim

We have a class 3 assembly we will be doing soon and I was wandering since the fillet heighth required for class 3 is 50% more than class 2, should I have my stencil thickness increased from 6 mil. to 7 mil.? This assembly is made up of 31 mil. pitch

In addition to robl's suggestions, I would look at the footprint on the board to make sure it meets the recommended dimensions. Abnormal layouts, particularly when pads extend under the component too far, can be problematic both by lifting the part

Hi all, Assuming that i were to design a PCB and there are multiple components, what is the minimum spacing required to ensure that i won't have problems in my SMT process later on? Also, is there a minimum component stand-off height spec as well?
