Conformal coatings are particularly useful for protecting circuitry in severe service environments, while maintaining a low stress environment for components and connections. These severe conditions range from every day temperature and humidity extremes seen in consumer electronics, to the more harsh automotive underhood applications, up to the ...
Definition. Conformal coating is a thin layer of protected polymeric coating applied to printed circuit boards (PCBs) and electronic components. Its goal is to provide environmental and mechanical protection for the components and circuits, allowing them to last longer and be more reliable. It maintains long-term surface insulation resistance ...
The manufacturing alert begins with summarizing the issue or problem. This can include the product, or product family, test issues and type (i.e., high failure at functional test), an assessment of what may be causing the problem (i.e., failure possibly related to a parametric test step that powers the units beyond product limits) and, when the ...
After PCB manufacturing, the copper traces on the substrate are left exposed to environmental conditions, like water and dust that can lead to oxidation.The best method of prolonging the PCB's lifespan is applying a protective coating known as a solder mask on the PCB surface. This article offers a comprehensive analysis of solder mask and how you can use it to inhibit problems, like solder ...
What is a Press-Fit Hole: Press-fit holes are placed in holes with a tolerance stricter than the +/-0,10mm norm. The press-fit hole size fits the connection leads, which are not soldered and forced into the hole. The tolerances are highly specified and tighter than the norm to permit the result and hole to precisely fit.
What PCBA processing plant need to do after resum ing work. If there is the "Best Accident of the Year" in 2020, I think it is the devil of new crown pneumonia. At present, thanks to the hard work of medical workers and strict prevention across the country, the eradication of the epidemic situation is just around the corner.
Burnt Circuit Board. Circuit board burns due to two basic reasons. First, if you apply high voltage, PCB will burn. Second, if the manufacturer uses low-quality components during the manufacturing process, the circuit board will burn. Every component works on a specific …
