What Does A SMT X-ray Machine Do?
Application of SMT X-ray inspection machine - Testing Chips The purpose and method of chip testing The main purpose of chip testing is to detect factors affecting product quality in the production process as early as possible and to prevent out-of-tolerance batch production, repair and scrap. Thi...Read more -
What Are Some Common PCB Dsign Mistakes?
As an integral part of all electronic devices, the world’s most popular technologies require perfect PCB design. However, the process itself is sometimes anything but. Sophisticated and complex, errors often occur during the PCB design process. As board rework can lead to production delays,...Read more -
What Is Buried Capacitor?
Buried capacitor process The so-called buried capacitance process, is a certain capacitive material using a certain process method embedded in the ordinary PCB board in the inner layer of a processing technology. Because the material has a high capacitance density, so the material can play a powe...Read more -
Maintenance of Selective Wave Soldering Equipment

What to Pay Attention to When Designing PCBA Circuit Boards？
1. Standard components should pay attention to the size tolerance of different manufacturers’ components, non-standard components must be designed in accordance with the actual size of the components pad graphics and pad spacing. 2. The design of high-reliability circuit should be widened s...Read more -
PCBA Process Control and Quality Control of The 6 Major Points
PCBA manufacturing process involves PCB board manufacturing, component procurement and inspection, chip processing, plug-in processing, program burn-in, testing, aging and a series of processes, supply and manufacturing chain is relatively long, any defect in one link will cause a large number of...Read more -
PCB Board Substrate Material Classification
Many varieties of substrates used for PCBs, but broadly divided into two categories, namely inorganic substrate materials and organic substrate materials. Inorganic substrate materials Inorganic substrate is mainly ceramic plates, ceramic circuit substrate material is 96% alumina, in the case of ...Read more -
Precautions for Manual Soldering of PCBA
In the PCBA processing process, in addition to batch soldering using reflow oven and wave soldering machine, manual soldering is also required to produce the product in its entirety. Matters needing attention when performing manual PCBA soldering: 1. Must operate with electrostatic ring, the huma...Read more -
