PCB Tolerances for Routing, Drilling, and Chemical Plating

Written by Jim Marsh
Posted on June 24, 2020 at 9:42 AM

Having been involved in the printed circuit board (PCB) world for nearly four decades, I continue to see the same drawing mistakes. When declaring PCB tolerances in any given design, the PCB designer must take into consideration the manufacturing of the board itself. In this blog post, we will review some of the issues we commonly see in PCB designs that are not allowing the proper tolerances for the routing, drilling, and plating processes.

In the rigid printed circuit board (PCB) world, you can easily generate a quote with cookie cutter specs, such as 0.062” thick, with FR4, green soldermask, and white silkscreen. With those standard specifications, you could quote a huge number of rigid PCBs.

How To Design PCBs - Engineering Advice on Details

Written by Jim Marsh

In front-end engineering, we must gather as much manufacturing information as possible from the printed circuit board data we receive. This includes customer service notes, customer emails, and the general spec, if available. Usually there is enough information to release a printed circuit board (PCB) package to manufacturing. However, I have found many gray areas that haunt our engineering department.

Combining PCB Surface Finishes on External PCB Layers

Written by Jim Marsh
Posted on February 26, 2018 at 11:05 AM

The reason printed circuit boards (PCBs) require a surface finish rather than being left as simply bare copper is because while copper is an excellent conductor, leaving it exposed will cause it to oxidize and deteriorate over time. The increased exposure will cause the PCB to fail much sooner than expected.
