For SMT chip processing, solder joint voids are a serious quality problem. The presence of voids will increase the oxidation of the product, leading to the deepening of the aging reaction of the product in advance. So, how do the hollows in SMT chip processing occur? Let the Shenzhen PCB manufacturer explain it for you……

Precautions for the use of solder paste in SMT patch processing: 1. Storage temperature: It is recommended that the storage temperature in the refrigerator is 5℃-10℃, and should not be lower than 0℃. 2. Outgoing principle: The principle of first-in first-out must be followed. Do not first-in-last-out, which may cause ……

How to program and produce the SMT placement machine is divided into two stages:One is offline preparation. The second is online debugging. Each factory has different specific details according to its own placement machine model and management mode. I will take our company process as an example. The offline preparati……

SMT operators mainly operate SMT related equipment, such as placement machines and solder paste printers. Deal with some simple faults to ensure smooth production.

SMT basic process components include: screen printing (or dispensing), placement (curing), reflow soldering, cleaning, testing, and repair 1. Silk screen: Its function is to print solder paste or patch glue onto the PCB pads to prepare for the solderin

ESD is the abbreviation of electronstatic discharge in English. The original meaning is electrostatic discharge, and usually refers to the protection of electrostatic discharge (that is, what we usually call electrostatic protection or anti-static)
