A Circuit Card Assembly (commonly referred to as a CCA) is a flat board with connected electronic components placed on it. CCA Manufacturing usually employs the use of machines (SMT and Through-hole) to automate the process of creating CCAs. Read More: What is SMT Manufacturing? Below is a video that quickly goes through what a CCA (sometimes called PCBA) actually is. Real World Uses of CCA From household items (TVs, microwaves, laptops, cell phones, smoke detector, security cameras) to industrial uses (medical imaging systems and monitors, automotive displays, power supplies, navigation systems), you can find CCAs in a many different industries. → Read More: What is a Circuit Card Assembly (CCA) and CCA Manufacturing?
There is a myriad of different CCA designs, types, and capabilities. However, PCBAs are largely comprised of 4 basic elements.
Substrate The material supporting all the electrical components together. Substrates can vary greatly depending on the type of PCBA. For example, you can have flexible, ridged, and metal core boards. Copper A thin layer of copper is laminated to the substrate of the PCBA connecting the electrical components with conductive tracks or traces. The number of copper layers depends of the type of PCBA, and can range from single-sided, double-sided, and multi-layer boards. Solder Mask Solder masks are applied as a coating to prevent corrosion, reducing the possibility of solder shorts. Silkscreen A silkscreen may be printed on circuit boards to display a legend identifying the components and test points. → Read More: What Are The Different Components of a CCA?
Printed Circuit Board Assembly (PCBA) and Printed Circuit Assembly (PCA) are both more informal terms that are commonly used in the industry, however the Intellectual Property Constituency (IPC) uses the term Circuit Card Assembly (CCA) instead. → Read More: Circuit Card Assembly (CCA) vs. Printed Circuit Board Assembly (PCBA. What's the difference?
SMT stands for Surface-mount Technology, and it is comprised on 3 primary machines: Stencil Printer, Pick and Place Machine, and a Reflow Oven. All these machines work one after the other to automate printing CCAs, reducing labor costs and increasing production rates.
Circuit Cards condition can worsen depending on humidity, duration of use, and wear and tear that affect performance. Before you recycle your CCA consider the possibility of repairing the board. A team of engineers will need to find out why your board is not functioning properly before you can proceed with a repair. Possibilities of Why Your PCBA is Failing Is your Circuit Card Assembly (CCA) failing you? Before you throw it out, try to determine why it's failing in the first place. Depending on the cause of the failure, you may be able to salvage your CCA and have it repaired by experts. Below are some reasons why your CCA may be having issues:
