How to Evaluate for Measle-Related Defects in a PCB? How do you test for measling in a circuit board? Here are some tips: Laminate Exposure to Moisture This is a special technique to evaluate measling in the PCB. The process involves: Exposing the PCB’s laminate to moisture. This must...
The “flying” probes are mounted on arms or heads controlled by precision robotic motion control to target test points anywhere on the PCB surface. Flying probes provide complete electrical testing coverage for assemblies ranging from simple boards up to complex multilayer PCBs with thousands of test...
How do you test for bad solder joints, especially if there are BGAs? What's the procedure for the assembly line to verify functionality before the PCB goes into the case? If a unit goes out with only 85% working the return cost is enormous. So part of that original design and ...
connections may be damaged, components may become loose, and materials may be damaged. To avoid these pitfalls, you need to choose the correct cleaning method just as carefully as you do when designing, specifying, and producing your circuit board. ...
Before leaving manufacturing houses, bare PCBs (Printed Circuit Boards) and PCB assemblies (PCBA) have to pass electrical tests so as to guarantee that boards go for high performance and high reliability in end products. Electrical tests are implemented to find out electrical and circuitry issues ...
test, depending on the size of the production lot. As all work to this point has occurred on boards as part of a panel (a note for new designers: you’re paying for services by the panel, not by the board), routing needs to be performed to remove the boards from the panel prior ...
Selecting the right dielectric material for high-density interconnect PCBs is paramount for ensuring optimal performance and reliability in electronic products. By considering operating frequency, signal loss, thermal, electrical, chemical, and mechanical properties, you can make informed decisions when selec...
Alternative Techniques for Attaching Wires to PCBs Even if you're a seasoned professional or an electronics hobbyist, the process of attaching wires to Printed Circuit Boards (PCBs) can feel intricate. Fortunately, options abound when it comes to attaching wires to PCBs. Let's delve into some ...
Designing test coupons for testing microvia reliability Test coupons are small PCB sections (typically 200x30mm). They are designed and manufactured alongside the main circuit board, with identical configurations. These coupons are used to assess the quality and reliability ofclass 3 PCBs. ...
2. Double-Sided PCBs Double-sided PCBs offer more real estate for your components and traces, enabling you to create more compact and sophisticated circuits. Etching both sides of the board requires careful alignment and planning, but the results can be impressive. ...
