I was wondering if anybody could tell me what a good clearance would be for board designs to allow for the use of inline equipment? My company currently runs a batch line but I want to make sure we are designing properly for inline if the need arises

There's no easy answer. It depends on: * Thickness and size of the PCB in the array. * Means of separation. * Type of component. SMT components are more sensitive to the forces that need to be applied to separate the PCB. * Type SMT device. Ceram

Hi, Is the IPC-A-610 applicable to CSP assemblies? Especially regarding the solder ball to solder ball distance versus the minimum electrical clearance for assembly(0.13mm/IPC-A-610). With a 0.4mm pitch component and 260 microns diameters balls, thi

We use a FKN pizza cutter and found that even with 5mm clearance and the proper orientation of the part larger ceramic capacitors 1812, 1210 would still stress fracture. We have successfully fixed stress fracture problems by adding routed relief slot
