What Are Laser Cut Stencils？ A Guide for PCB Assembly
Traditional PCB assembly processes require the manual placement of electronic components before soldering. However, the increasing complexity of electronic printed circuit boards, combined with the need for miniaturisation, necessitates mechanical assembly and solder paste application using SMT stencils. Placing and soldering many small components on a small circuit board is no longer practical.Stencils replace the hand soldering of surface mount components and the inconsistencies caused by hand solde......

SMD Stencils in Prototyping vs Mass Production
SMD stencils are known for mass production and easy solder paste dispensing. They are widely used in the industry. The stencils are very useful when you are mass-producing a unit. Today, we are not going into physics or manufacturing but talking about the different use case scenarios. However, the stencil requirements for prototyping are quite different from those in mass production. In mass production, we need yield, the better the yield more efficient the production. For these needs, JLCPCB offers c......

Design Guidelines for Industry-Standard Solder Stencil
Solder paste printing is one of the most important processes in PCB assembly, and the design of a stencil directly affects the quality of solder paste application. In a previous article, we discussed stencils and their types in detail. JLCPCB’s advanced stencil options, including step-up/step-down and nano-coated stencils, help engineers achieve higher printing accuracy and assembly reliability. In electronics hardware design, following proper design rules is just as crucial as having the right tools.......

Unlocking the Secrets of Nano-Coated Stencil Manufacturing
Nano-Coated Stencil Manufacturing Process The manufacturing of nano-coated stencils involves a series of precision engineering steps including design and drafting, laser cutting, polishing, nano-coating deposition, and quality inspection. Below is a detailed description of each process stage: 1. Design and Drafting (1) Data Acquisition: Accurate data is obtained from customer-supplied design files (e.g., Gerber files, PCB layouts) or physical product samples. This includes stencil dimensions, pad layo......
