What Are The Methods to Improve PCBA Board Soldering?
In the process of PCBA processing, there are many production processes, which are easy to produce many quality problems. At this time, it is necessary to constantly improve the PCBA welding method and improve the process to effectively improve the product quality. I. Improve the temperature and t...Read more -
Circuit Board Thermal Conductivity and Heat Dissipation Design Processability Requirements
1. Heat sink shape, thickness and area of the design According to the thermal design requirements of the required heat dissipation components should be fully considered, must ensure that the junction temperature of the heat-generating components, PCB surface temperature to meet product design req...Read more -
What Are The Steps for Spraying The Three-proof Paint?
Step 1: Clean the board surface. Keep the board surface free of oil and dust (mainly flux from the solder left in the reflow oven process). Because this is mainly acidic material, it will affect the durability of the components and the adhesion of the three-proof paint with the board. Step 2: Dry...Read more -
Safety Measures for Manual Soldering
Manual soldering is the most common process in SMT processing lines. But the welding process should pay attention to some safety measures in order to work more efficiently. Staff need to pay attention to the following points: 1. Due to the distance from the soldering iron head 20 ~ 30cm at the co...Read more -
What Does A BGA Repair Machine Do?
BGA soldering station introduction BGA soldering station is also generally called BGA rework station, which is a special equipment applied to BGA chips with soldering problems or when new BGA chips need to be replaced. Since the temperature requirement of BGA chip welding is relatively high, so t...Read more -
Classification of Surface Mount Capacitors
Surface mount capacitors have developed into many varieties and series, classified by shape, structure and usage, which can reach hundreds of kinds. They are also called chip capacitors, chip capacitors, with C as the circuit representation symbol. In the SMT SMD practical applications, about 80%...Read more -
The Importance of Tin-lead Solder Alloys
When it comes to printed circuit boards, we cannot forget the important role of auxiliary materials. Currently, the most commonly used tin-lead solder and lead-free solder. The most famous is 63Sn-37Pb eutectic tin-lead solder, which has been the most important electronic soldering material for n...Read more -
Analysis of Electrical Fault
A variety of good and bad electrical failure from the probability of the size of the following cases. 1. Poor contact. Board and slot poor contact, the internal fracture of the cable does not work when it passes, the line plug and terminal contact is not good, components such as false welding are...Read more -
Chip Component Pad Design Defects
1. 0.5mm pitch QFP pad length is too long, resulting in short circuit. 2. PLCC socket pads are too short, resulting in false soldering. 3. IC’s pad length is too long and the amount of solder paste is large resulting in short circuit at reflow. 4. Wing-shaped chip pads are too long to affec...Read more -
Wave Soldering Surface Components Layout Design Requirements
I. Background description Wave soldering machine welding is through the molten solder on the component pins for the application of solder and heating, due to the relative movement of the wave and PCB and molten solder “sticky”, wave soldering process is much more complex than reflow s...Read more -
Tips for Selecting Chip Inductors
Chip inductors, also known as power inductors, are one of the most commonly used components in electronic products, featuring miniaturization, high quality, high energy storage and low resistance. It is often purchased in PCBA factories. When selecting a chip inductor, the performance parameters ...Read more -
How to Set Parameters of Solder Paste Printing Machine?
Solder paste printing machine is an important equipment in the front section of SMT line, mainly using the stencil to print the solder paste on the specified pad, the good or bad solder paste printing, directly affect the final solder quality. The following to explain the technical knowledge of t...Read more
