High-Quality PCB Assembly Service FR-4 DIP Coating Service With Material Accuracy 0402+BGA 0.5mm

FR4 material widely used in PCB Assembly

FR-4 material is the most successful and widely used material in PCB processing for many years. This is mainly because, although FR4 substrates contain similar properties and are mostly epoxy resin systems, this range is wide. As a result, today's FR4 materials are commonly used in the most common terminals. For relatively simple applications, FR4 materials with TG values of 130-140°C can be selected. FR4 material with TG value of 170-180 should be selected for multi-layer or thick FR4 circuit boards that have high requirements on heat resistance. With the advent of lead-free welding technology, TD and other indexes besides TG should also be considered together. In addition, higher TG values do not always mean better performance in lead-free welding applications. In other words, as terminal applications expand, so will the range of FR4 materials available.

PCBA Testing Services

Our PCBA facility is equipped with state-of-the-art testing and validation equipment. Finished PCB components are checked for proper component placement and functionality through a variety of methods, including AOI inspection, in-circuit testing, and x-ray inspection.

PCBA SMT processing is very complicated and includes multiple important processes, such as PCB board manufacturing process, component procurement and inspection, SMT assembly, DIP, and PCBA testing. Among them, PCBA testing is the most critical quality control step in the entire PCBA processing process. The testing determines the final performance of the product.
