What is a Blank PCB?
Introduction A blank PCB, often referred to as a bare board or printed circuit board, is an insulating substrate with pre-etched conductive copper traces (circuitry) and drilled holes for mounting electronic components. However, it has not yet been populated with any electronic components (such as resistors, capacitors, chips, etc.). Think Read more

What Does PCBA Mean? What’s the Difference Between PCBA and PCB?
Introduction Printed Circuit Board Assembly (PCBA) involves assembling various electronic components onto a Printed Circuit Board (PCB) to create a functional electronic device. This process is crucial in electronics manufacturing. It transforms a bare PCB, lacking components, into a fully functional unit. The PCBA serves as the core of many Read more

What is a Varistor? What is its Role on a PCB?
The image above shows a real varistor. You might mistake them for capacitors. However, varistors and capacitors don’t have much in common besides their size and design. Varistors are used to suppress voltage surges, a function capacitors cannot perform. A varistor is a resistor whose resistance changes with the voltage Read more

What is FCT in PCB Manufacturing?
Introduction If you work in the printed circuit board (PCB) industry or simply use electronic devices, you know that post-production testing is crucial before any device reaches the market. Functional Circuit Test (FCT) is a key step in the PCB Assembly (PCBA) quality control process and a fundamental skill that Read more
