Method for Quality Inspection of PCB
1. X – ray pick up check After the circuit board is assembled, X-ray machine can be used to see the BGA underbelly hidden solder joints bridging, open, solder deficiency, solder excess, ball drop, loss of the surface, popcorn, and most often holes. NeoDen X Ray Machine X-Ray Tube Source Spe...Read more -
Advantages of PCB Assembly Prototyping for Rapid Construction of New Products
Before starting a full production run, you need to make sure your PCB is up and running. After all, when a PCB fails after full production, you can’t afford costly mistakes or, worse, faults that can be detected even after you put the product on the market. Prototyping ensures early elimina...Read more -
What Are The Causes and Solutions of PCB Distortion?
PCB distortion is a common problem in PCBA batch production, which will bring considerable influence to assembly and testing. How to avoid this problem, please see below. The causes of PCB distortion are as follows: 1. Improper selection of PCB raw materials, such as low T of PCB, especially pape...Read more -
Requirements for The Layout Design of Components for Wave Soldering Surface
1. Background Wave soldering is applied and heated by molten solder to the pins of components. Due to the relative movement of wave crest and PCB and the “stickiness” of molten solder, the wave soldering process is much more complex than reflow welding. There are requirements for pin ...Read more -
6 Limitations of Selective Wave Soldering Machine
Selective wave soldering machine provides a new welding method, which has incomparable advantages over manual welding, traditional wave soldering machine and through-hole reflow oven. However, no welding method can be perfect, and selective wave soldering also has some “limitations” d...Read more -
What Is The Difference Between Laser Welding and Reflow Welding?
Introduction to reflow oven Reflow oven uses flux coating, then preheating circuit board/activated flux, and then using welding nozzle for welding mode. The traditional artificial soldering iron welding needs to use point-to-point welding for each point of the circuit board, so there are more wel...Read more -
What Are The Advantages of SMT Processing Technology?
SMT processing process: First on the surface of printed circuit board solder coating solder paste, again with SMT machine components of metallized terminal or pin accurately on the bonding pad of solder paste, then put the PCB with components in the reflow oven whole heated to melting solder pas...Read more -
What Does a Selective Wave Soldering Machine do?
Selective Wave Soldering Machine Types 1. Mask selective wave soldering Mask selective wave soldering is a selective welding process that uses mask to expose the welding areas and cover the areas that do not need welding. It is widely used and suitable for the production of small and medium batch...Read more -
How to realize conductive hole plug hole process?
For SMT board, especially for BGA and IC pasted on the conduction requirements must level off, the plug hole convex concave plus or minus 1 mil, can not have guide hole edge on the red tin, guide hole is Tibetan beads, in order to meet customer requirements, conducting plug hole process is multif...Read more -
How to quickly estimate the resistance of PCB surface copper wire?
Copper is a common conductive metal layer on the surface of a circuit board (PCB). Before estimating the resistance of copper on a PCB, please note that the resistance of copper varies with temperature. To estimate the resistance of copper on a PCB surface, the following formula can be used. When...Read more -
What Does An SMT AOI Machine Do?
SMT AOI Machine Description AOI system is a simple optical imaging and processing system integrated with cameras, lenses, light sources, computers and other common devices. Under the illumination of the light source, the camera is used for direct imaging, and then the detection is realized by com...Read more -
What Does A Wave Soldering Machine Do?
