| | | We are all faced with increasing interconnect density in all we do. This means smaller everything, especially components and that which they are mounted upon but, hopefully, without smaller minds and thoughts. It all demands more process contro

Thanks for the information. So Density level A corresponds to "88", B to "55" and C to "44" ? Im wondering why the difference in naming ? Thanks

The 3-Tier PCB library concept was originally created by IEC (International Electromechanical Commission) in 1999 and introduced to IPC in 2000. The concept had to be created as a solution for high density packaging for hand held devices to ruggedize

I am planning a PCB design for automated assembly of all components, SMT. I have been told that the industry standard used at the assembly house is something called "88", and that the assembly house can do better "55" or even "44". I’m not sure if

Not sure how 88, 55 and 44 tie to other things, but if you talk IPC, you'll have a point of reference that's portable between suppliers
