An Introduction to Automated Optical Inspection (AOI) by PCBGOGO
Automated optical inspection (AOI) is an important process used in PCB fabrication and test of printed circuit boards. It plays an effective and accurate role in detecting the electronic assemblies and your PCBs to make sure the product has a high quality leaving the production line and your PCB without any manufacturing faults .

An Introduction to Electroless Nickel Immersion Gold (ENIG) by PCBGOGO
Electroless nickel immersion gold (ENIG) process has been widely used in PCB fabrication, which is an auto-catalytic process that is related to deposition of nickel on the palladium-catalyzed copper surface. And it will provide the appropriate concentration, temperature and pH levels necessary to create a consistent coating that need to replenish the reducing agent with nickel ions. The gold adheres to the nickel plated areas by molecular exchange during the immersion gold process to prevent the nickel from being oxidized until the soldering process arises. What’s more, the thickness of gold needs to meet the demands of certain tolerances so that make sure the nickel has a great solderability.

Explaining Reflow Soldering for PCB Assembly by PCBGOGO
When it comes to PCB assembly process, reflow soldering is the most widely used method of soldering, which is widely used for PCB assembly. It offers credible soldering for the all kinds of the sizes of component and pad required, as well as making it easy to control. The purpose of reflow soldering is to be acceptable soldering joints with pre-heating the components/PCB/solder paste first and then melting the solder, which instead of overheating without damage.

An Introduction of Organic Solderability Preservative (OSP) by PCBGOGO
Over the years, electronic products are developing towards light, short, miniaturized and multi - functional. As well as high precision, high speed, high density and so on. However, hot air leveling process is increasingly unsuitable for the demands of PCB fabrication process as the rapid development of SMT. At the same time, the soldering material, such as Sn-Pb, which can’t meet the demands of environmental requirements for hot air leveling process.

Explaining Laser Direct Imaging in PCB Fabrication by PCBGOGO
when it comes to a prototype circuit board, PCB layout is one of the most important aspects. taking into account the smallest things goes wrong, the entire board will be damaged and it will not function appropriately, so PCB layout is extremely important. The imaging process, one of the most important steps in the PCB assembly process, and it does well in creating the PCB pattern.
