Not to be off-topic, but push engineering for embedded passives and remove parts from the underside all together. Watch the material cost sky rocket, but watch the manufacturing cost sink and well as improve the production cycle by 50%. Sorry, I w

Hi If this is the tombstoning I know which is evidenced by parts touching each other and some obvious colored material at the edges just wash them again real good. Now you might want to do some IR tests just in case you will have a reliability hit.

Increasing the score depth enough to make manual depaneling safe may very well make the panel useless, depending on your automated processes and handling requirements and methods. We use depanelers daily, hourly, even. We prefer to route the boards

Hello Mike, The IPC has recently released a specification (IPC-9850) that characterizes the performance of placement machines. The process is very similar to the process you describe (placing parts on a glass plate and measuring the results). The I

Does anyone know of any free software that would allow an inspector to look for a reference designator on a densely-populated PCB? The software would need to accept a CAD pick'n'place file as input, and highlight the part when the inspector enters t

Tell us more about your printer. squegge blade type ,speed, snap-off distance etc... You shouldn't have to change apertures for any component based upon its rotation. the parts that are coming out good could they withstand a higher volume print? You
