We recently had a multi block panal change at the vendor Now the production lines are producing solderability defects in great number. The makeup of the pcb is a type of fiber glass mask green in color and pads with no tinning just copper lands.

For a single board that takes 5 minutes to build on my machine, is it better to do it as a single board or a 4 up panalized board that will take 20 minutes to build? And why?

AJ, you are making this harder than it realy is. Import the cad file with the BOM. Then use the panalize function built into Flexa to step and repeat for block 2 and 3. The ref. designators will be tied to each block (board).

Listen, you should try to utilize wave solder as well. High speed gadgets are fine if you want to make things complictded, but if your just starting things up, think simple. Nothing beats wave for solder many parts at the same time. If you can't p

To clean up other replys I will add that some most all machines have global correction. Most placements are an off sets from pcb 0,0 usually the lower left corner of the board. When the machine locates the fiduitals and these fids are not exactly whe

Fractured parts that we've seen at reflow in the past are related to trapped moisture in the part, out-gassing at temp, and fracturing the part. I have seen this on ceramic resonators in the past; don't know why this type of part seems prone to this
