Web1) For PCB boards that need to be inserted and removed frequently, gold fingers usually need to be plated with hard gold in order to increase the wear resistance of gold fingers. 2) The gold finger needs to be chamfered, usually 45°, and other angles such as 20°, 30°, etc. If there is no chamfer in the design, there is a problem. Web8 aug. 2024 · IPC has a High Temperature PCB Flatness Guideline, IPC-9841, a standard that provides local area PCB warpage information across reflow profile temperatures. The guidelines help in selecting necessary measurement equipment, planning testing, and preparing PCBs for test, and conducting measurements across reflow temperatures.
