Product Description

PCB Proofing Black Soldmask SMT PCB Assembly Electronic Printed Circuit Board PCBA



What is SMT PCB Assembly?


SMT, short for Surface Mount technology, refers to a SMT assembly technology for attaching components (SMC, surface mount components or SMD, surface mount devices) to expose PCBS (printed circuit boards) through the application of a range of SMT assembly devices.

The Importance Of PCB Proofing

PCB proofing is critical for mass production as it provides an opportunity to optimize the final mass production stage. When your product enters the mass production stage, proofing production means higher efficiency, which means lower costs. PCB proofing production is the last chance to uncover potential difficulties that may arise later in the production cycle. How can we help our customers before large-scale production of PCBS? Working with us you can get help at every stage of the PCB production cycle, our team is very aware of the need for smooth production, and we know that errors can be costly to ensure that PCB manufacturing is performed correctly throughout the mass production phase of the product cycle.

SMT PCB Assembly Inspection Necessity

In order to ensure the quality and performance of the assembled PCB, it is very necessary to check during the entire SMT assembly process. Multiple types of inspections must be used to reveal manufacturing defects, which can reduce the reliability of the final product.

Visual inspection is most commonly used in SMT patch assembly. As a direct inspection method, visual inspection can be used to indicate obvious physical errors, such as component displacement, missing components, or component irregularity.

Visual inspection is not suitable for visual inspection. Tools such as a magnifying glass or microscope can also be used. In order to further point out the defects occurring in the welding ball, AOI and X-ray inspection can be used after the completion of coal bonding
