What’s the PCB prototype board?
The PCB prototype board refers to the testing prototype board before mass production. It is mostly used by electronic design engineers to produce small batch test production to the PCB factory after designing the PCB and completing the DRC analysis of the PCB, this is...
Printed circuit boards have bare boards and PCBA, what is the difference between them, PCBA is PCB assembly, is a circuit board with components, it has actual functions. So you will know PCB just is bare PCB without any components. PCB is the abbreviation of Printed Circuit Board, also known as circuit...
What’s FR-4 material?
FR-4 material, which is the abbreviation of fiberglass cloth, the full name of FR-4 is “flame retardant”. It means a material that does not spread flames and meets UL94V-0 flame retardant standards. It is a commonly used raw material and substrate for circuit boards,...
Copper board PCB is a commonly used circuit board that plays an important role in electronic devices. It comprises several parts, such as substrate, copper foil, anti-etch layer, and printing ink. The substrate is the main body of the circuit board, usually, a glass fiber plate; copper foil is the conductive...
Pre-assembly PCBA TestPCB: The PCB is tested for short circuits or any technical problems through test points.
Components: Before assembly, each component is tested to see if its parameters are the same as those in the BOM if its package is the same, and if it is damaged or unusable.
Bitmap: Check...
Common Techniques Involved in the PCB Routing Process
The intricate pathways etched onto a PCB, known as traces, are the vital lifelines that connect electronic components and allow signals to flow. This meticulous process of defining these pathways is called PCB routing. Mastering PCB routing techniques...
