Custom Electronic SMT FR4 Multilayer PCBs Prototype Black White Silk Screen PCB Assembly
SMT Stencil Used In The PCB Design
Surface Mount Technology (SMT) templates are made of a thin,
flexible material with openings corresponding to the pads of the
components and holes in the PCB. The opening in the template allows
conductive ink to flow during PCB etching. They are a great way to
quickly and accurately apply solder paste to the pad on the circuit
board. PCB templates help save money, improve quality and speed up
the manufacturing process. Templates can be used for single or
multi-layer boards, as well as multi-layer large boards. At Sky
Win, we offer a wide range of rugged SMT Stencils to suit your
specific manufacturing needs, manufacturing methods and components
used in your board.

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
