Home » Questions » PCB Assembly » What’s the meaning of “CR” marked on the PCB?
C for capacitance. R for resistance. CR for capacitive reactance circuit.
Alternating current can pass through the capacitor. When the capacitor is connected to the AC circuit, the charge on the capacitor plate has a hindering effect on the directional moving charge, which is called the capacitive reactance.

In my current prototype, I have a SIMCOM GSM module and the gp-635t GPS. They are both in an enclsoure including antennas (gps antenna is integrated). What I experience is sometimes poor GSM and GPS connectivity and sometimes GPS doesn’t get any fix (in the 2 minutes of time i allocate for it) and the GSM fails to send data sometimes. Any tips on this case?
I am a buyer in a telecom company. Recently, an important order of SMT PCBA is delayed due to insophiscated production of a supplier. I am thinking about replace it and just very puzzled about how did their SMT pad fall off easily when soldering the PCB boards. That slows down the whole process.
I have received the final prototypes from manufacturer and all is good after our checking. And we want to keep it well. Do you have any tips about that?
Flawless PCB soldering is imperative for proper functioning of a printed circuit board. However, even experienced technicians can make small mistakes that lead to soldering defects.
What Is Prototype PCB Assembly? Prototype PCB assembly refers to the experimental phase that follows the PCB design to demonstrate the feasibility of the design
When assembling printed circuit boards, engineers have two main techniques to choose from: through hole and surface mount technology (SMT). In the early days, we dealt
