How to Avoid Copper Peel Off

Hot Air Solder Leveling (HASL) involves coating the surface of the exposed copper with a layer of tin alloy to prevent oxidation and provide a good soldering surface for subsequent assembly. The basic process of HASL is to briefly immerse the PCB board into a high-temperature liquid tin bath. Through the action of flux and high-temperature tin, a copper-tin alloy (IMG) is formed. Then, on guide rails, the board is lifted out while high-pressure gas blows away excess tin from non-copper areas and level......

Technical Guidance: Mouse Bite Panelization Guide

The conventional method of panelization uses V-grooves. However, for irregularly-shaped boards or special requirements (such as JLCPCB's economic SMT assembly), mouse bite panelization, which resembles postage stamps on an envelope, is required. PCBs panelized using this method are called "mouse bite panels" or "mouse bite connections". Mouse bite panelization can be referred to as "universal panelization." As long as there is a position to add mouse bites, boards of various shapes can be interconnect......

How to Choose the Right Surface Finish for Your PCB

When it comes to designing and manufacturing of printed circuit boards (PCBs), considering the element of your surface finish is a critical decision. In addition to influencing the PCB's aesthetics, surface finish is essential to the functionality, dependability, solderability and longevity of the electronic equipment it powers. The surface finish serves as a protective layer on the exposed copper traces of a PCB. It prevents oxidation, promotes solderability, enhances conductivity, and provides a lev......
