Hi In my experience try to change component to another batch or anther manufacturer it is very often problem in reflow when components have strange finish

Hello! I've had the same problem about one Jear ago. We had exessive building of voids in the solder joints. I recomment to take a pincer to break off some of the components. If the solder joint is good, the copper pad will stay at the solder joint

Have some option to fix it by glue with dispenser? Did you check mby that component touch something inside oven?

We use similar switch and the same oven. You need to modify the stencil, increase surface area. Have modified all our stencils to the point where we no longer use inline glue dispensers for any product

i have 1 customer using our reflow oven, he is facing the problem that after taking the boards from reflow oven ICs & some resistors felt down.they are using our glue dispenser also, the glue is not fixed with the component. wht will be the solution

Does any one know how to calculate BGA height change after reflow oven? I guess the calculation will be based on the component size, weight, ball diameter and ball count of the BGA, but how to get the actual height?

Dial indicator on a post/base. You might need a fine point tip to get between adjascent components and the BGA. Or... if you're real fance schmancy you could use a CMM if you have one.

We are reflowing ceramic resonators and are finding their tops falling/popping off when handling the pcbs during final assy. The epoxy seems to be coming off the components base and adherring to the lid. The components are "RFM resonators", case type

Hello Craig Are code dates other than these two coming apart or do they stay together? If other dates stay together you should get together with RFM. Did the process work before and and the defects just start happening? These are pictured on the RFM
