With 0402 components becoming more common today outside of the telecommunications industry, our company is qualifying equipment and processes for an upcoming product incorporating 0402s. Having used 0402s in a previous position, I am planning a DOE o

Please your comments for placing 0402 on CP4? Which are the difficulties to expect and how to threat them? How to adapt the feeders for the smaller interdistance of the tape?? Thanks

You're correct. This design will have a record amount of 0402 rework for tombstoning and misalignments. Suggest that the pads on each end of all components be the same size in order to balance wetting forces during reflow.

Short answer is - not really. According to the manual in Chapter 1-5 Supply devices (Feeders) overview "There are also available an 8mm tape feeder which handles 1005(0402) square chips". I have never seen one. The problem is that even an H nozzle is

Hi All, One of my customer has provided a pcb design having common pad for 0402 and 1206 package(i.e 3 pads in the gerber, pad1,pad2 belongs to 1206 package and pad2,pad3 belongs to 0402 package) Will this create any solderability issue. Is anyone e

Hello I have a new 0402 pad design on a recent board were building in future. On closer look i thought the pad was a thru hole mount , but upon closer inspection the round pads are for 0402 comps. I had a discussion with the engineer and he said

whats your board finish?

The first issue I see is that you have a high potential of the 402 tombstoning.

Does any one out there know if CSM84V and CSM84VZ can do 0402 parts ? If so, do they actually make 8mmx2mm feeders for these machines. I've had someone tell me they do, but i can't seem to find those feeders anywhere. thank you

We are currently experiencing a high rate of false calls on our 0402 chips. Resistors for the most part. Has anybody out there found a setting where this false calls are minimized? We are using top red light, pattern inspection,color inspection ( wh
