PCB AssemblyIn our ongoing series describing the more common problems associated with printed circuit boards, we examine design, assembly, and manufacturing issues. Next, we'll focus on some issues that can affect the board during assembly. While some of
PCB manufacturing principle processThe manufacturing process of PCB is relatively complicated, and there are many process requirements. In fact, there are many specific manufacturing processes on the Internet. Let’s talk about the principle of PCB. PCBs a
When SMT components are placed, connectors are placed first, followed by power circuits, sensitive and precision circuits, critical circuit components, and any other required components. You are selecting route priorities based on power level, noise sensi

Three anti-paint coating is the last link of SMT patch. If there is no mistake in the previous welding and testing assembly, we can ship after this process is completed. Manual coating and machine spraying are two common three anti paint coating methods,
First, the cause of virtual welding/false welding?The oxidation of the pad and the pin of the component is easy to cause that the solder paste in the state of liquefaction cannot fully infiltrate the pad and climb the tin during reflow welding, resulting
When welding, we should ensure that there is tin around the solder joint to prevent virtual welding, but it is not the more tin the better, when the solder joint tin cone layer is the best. When welding the circuit board, it is also necessary to pay atten
The current design of this wrist sphygmomanometer solution, can provide the main control chip (IC), with the production materials of PCBA, or provide the module (PCBA), with complete operation instructions and technical solutions, to cooperate with the fa
In the printing process, the pressure of the scraper should be adjusted, the appropriate steel mesh should be selected, and the steel network port should not be too small to avoid the situation of too little tin.adjust the reflow welding temperature curve
Medical PCB assembly requirements and oximeter PCBA case analysisIn clinical practice, many medical devices play a key role in saving patients. These medical devices include oximeters, ventilators, mobile CT, patient monitors, extracorporeal membrane oxyg
PCB production processThe minimization of all solder joint defects should be the goal of any SMT manufacturer. By understanding defects, their root causes and how to prevent SMT placement defects, you can greatly improve the quality of all the components
Introduction to Consumer Electronics PCBAAfter the PCBA board completes the front-end welding process, it is still impossible to ensure that the PCBA board is intact. In order to ensure that the products shipped to customers are intact and improve custome
