2020年9月22日 · To clean a corroded or oxidized PCB, Use cotton swabs and a cleaning solution such as isopropyl alcohol, baking soda and water, or even vinegar to clean it. Gently apply the solution to the affected area and wipe back and forth until the corrosion is removed.

2008年6月17日 · HI all, what is the best way to protect RF PCB from the corrosion. any coating should be done to protect, if so pls suggest any method/material. ( RF PCB consists of 2.45GHz transceiver+PA+PCB antenna) thanks roshni Added after 3 …

2014年3月6日 · What you measure is not just the filter. Your measurement includes the connectors, the transition from connector to the PCB and the filter. On the PCB you have 50 Ohm lines, but between the connector (the coax part) and the beginning of the microstrip line you have a long metal pin (the center conductor of the connector) that does not have 50 Ohm.

2011年5月7日 · From non-RoHS to RoHS conversion, only change is the FAB (PCB). In earlier non-RoHS boards RoHS components were used. So can we consider RoHS modules are G3 corrosion resistant without testing. Can you also refer me to some good links where can I refer about G3 corrosion. Regards SC

2017年6月27日 · We have a 4 layer, FR4 power supply PCB which lies on a large earthed heatsink. We want to heatsink the power FET to the heatsink. It dissipates 13W. We would like to have a cutout in the PCB, which will be underneath most of the D2PAK FET’s body and drain tab.

2007年11月10日 · With "ALL" I really mean all 8 pins. With "IC pins" I really mean the pin at the IC and not the signal at the PCB. The PCB layout is not optimal (Again: I don´t expect the layout problems to cause the cold start problem) * the power input connector is on the left side of the PCB, output on the right side.
