What Components Should Be Tested On A PCB and PCB assembly?

All electronic products need to be tested even if they are accurately designed and professionally fabricated, as they can be prone to malfunctions and problems. Printed circuit boards are composed of various electrical components which need to function correctly, and PCB testing is essential to test that each component is functioning. Capacitors Testing a capacitor in a printed circuit board requires one end of the capacitor to be removed from the circuit board. Then, it’s essential to make sure that the power supply of DC voltage matches the range of the capacitor to prevent overloading of the device. When you [...]

Why You Need 3D X-Ray Testing- Printed Circuit Board Assembly-Hitech PCB

Printed circuit board assembly has come a long way in recent years. Now that PCB assembly can easily be performed by machine, PCB manufacturers have been able to increase their production and drastically reduce the time required for this process. In fact, a few PCB assemblers even offer standard turnaround times of three days or less -- 75% faster than the industry average. However, clients who rely on these circuit boards will never be willing to sacrifice quality for speed. In order to ensure PCB production maintains a high-quality standard and exceeds customer expectations, PCB assemblers must prioritize testing during [...]

Types of PCB Failure analysis test

1.Micro-Sectioning Analysis Micro-sectioning also know has cross-sectioning or metallographic preparations are used for PCB testing. Thermo-mechanical failures Component Defects Opens or shorts Processing failure due to solder reflow Raw material evaluations   2.Solderability Testing Solderability test work for a variety of applications and quality standards PCB Coating Evaluation Solder Evaluation Flux Evaluation Benchmarking Quality control The PCB failure analyst should have the experience to differentiate the various conditions and understand the requirements of the testing technique   3.PCB Contamination Testing Contaminations can be the reason for part failure including degradation metallization Processing of printed circuit boards is taken place in [...]

Something About Automated Inspection Systems

Automated Optical Inspection (AOI) is as the name suggests a visual quantitative and qualitative test for PCBs. This automatic process allows companies to reduce their dependency on manual testing and thereby lessen any chances of human error. Since testing is an important process when it comes to the products provided by PCB assembly service providers, AOI systems offer immense reliability.   Need for Robust Testing Systems PCBs need to be produced according to certain guidelines put forth by leading organizations and Government bodies. Some specific reasons to opt for AOI testing include: AOI testing is an automated optical system. This [...]
