Hello,
Recently i lost a contract for a small PCB layout for a xenon flashlamp.
I lost the contract because a rival agency layed the PCB out using nominal footprint sizes for the SMT resistors and capacitors........i instead made the footprints as big as the maximum 0603, 0805, 1206 etc footprint, and then added an extra 0.2mm on each end, to allow for slightly mispositioned components....
...as a result of making the footprints bigger, i did not have enough room for a ferrite bead that was needed for filtering for a particular customer, so i lost the contract.
But surely what my competitor did was wrong......i mean, if a large tolerance end batch of resistors comes in, then the resistors will have their ends sitting off the pad, and on the solder resist, which will denigrate the solder joint.?
I recomended making the pcb bigger and using my ample size footprints...but they binned me and went with the competitor...... is this right?
