Precautions for PCB Welding
1. Remind everyone to check the appearance first after getting the PCB bare board to see whether there is short circuit, circuit break and other problems. Then get familiar with the development board schematic diagram, and compare the schematic diagram with the PCB screen printing layer to avoid ...Read more -
What Is The Importance of Flux?
NeoDen IN12 reflow oven Flux is an important auxiliary material in PCBA circuit board welding. The quality of flux will directly affect the quality of reflow oven. Let’s analyze why flux is so important. 1. flux welding principle Flux can bear the welding effect, because the metal atoms are...Read more -
Causes of Damage-Sensitive Components (MSD)
1. The PBGA is assembled in the SMT machine, and the dehumidification process is not carried out before welding, resulting in the damage of PBGA during welding. SMD packaging forms: non-airtight packaging, including plastic pot-wrap packaging and epoxy resin, silicone resin packaging (exposed to ...Read more -
What Is The Difference between SPI and AOI?
The main difference between SMT SPI and AOI machine is that SPI is a quality check for paste presses after stencil printer printing, through the inspection data to solder paste printing process debugging, verification and control; SMT AOI is divided into two types: pre-furnace and post-furnace. T...Read more -
SMT Short Circuit Causes and Solutions
Pick and place machine and other SMT equipment in the production and processing will appear a lot of bad phenomena, such as monument, bridge, virtual welding, fake welding, grape ball, tin bead and so on. SMT SMT processing short circuit is more common in fine spacing between IC pins, more common...Read more -
What’s The Difference Between Reflow and Wave Soldering?
NeoDen IN12 What is reflow oven? Reflow soldering machine is to melt the solder paste pre-coated on the solder pad by heating to realize the electrical interconnection between the pins or welding ends of electronic components pre-mounted on the solder pad and the solder pad on the PCB, so as to a...Read more -
How Much Does A Pick and Place Machine Cost?
The amount of automatic pick and place machine depends mainly on the following factors: 1. Origin of SMT machine There is probably several times the price difference between the automatic surface mount machine made in China and that made in other countries. The price of other countries’ aut...Read more -

Why Is Flux So Important for PCBA Circuit Board Welding?
1. Flux welding principle Flux can bear the welding effect, because the metal atoms are close to each other after the diffusion, dissolution, infiltration and other effects. In addition to the need to meet the removal of oxides and pollutants in the activation performance, but also to meet the no...Read more -
What are The Advantages and Disadvantages of BGA Packaged?
I. BGA packaged is the packaging process with the highest welding requirements in PCB manufacturing. Its advantages are as follows: 1. Short pin, low assembly height, small parasitic inductance and capacitance, excellent electrical performance. 2. Very high integration, many pins, large pin spaci...Read more -
