When choosing smaller parts, consider ImAg or ENIG instead. The board surface names HAL and HASL (hot air leveling and hot air surface leveling) refer to the same thing. They are interchangeable terms. With that out of the way, I’ll get to my point, which is HASL is not the right surface for all app...

Question: I don’t understand why my etch pads are not big enough for my vias. I thought I allowed plenty of room for annular ring. Why is that? As designs get more compressed, conductors, spaces and pads continue their march to be smaller and smaller. Designers are left trying to squeeze pad sizes i...

Voltage Drops across Traces and Vias
Overcoming problems of nominal dimensions of the trace and board to calculate resistance.
by Douglas Brooks, Ph.D., and Dr. Johannes Adam

http://pcdandf.com/pcdesign/index.php/magazine/11478-noise-control-1703

Designers and engineers are sometimes concerned about the voltage drop across a trace. With today’s low impedance circuits, such voltage drops may introduce an unacceptable amount of noise or signal level uncertainty into a circuit. These engineers are also concerned about the potential voltage drop...

A WiFi module was soldered to one of several different product-specific carrier PCBs. The module is an eight-layer ELIC PCB, 30 x 40mm and 0.77mm thick, fabricated with a mid-Tg, halogen-free laminate. The module has an LGA pattern with 333 pads 0.6mm2 and ENIG surface finish. There are several conf...
