How to reduce the surface tension and viscosity in PCBA soldering?
I.Measures to change surface tension and viscosity Viscosity and surface tension are important properties of solder. Excellent solder should have low viscosity and surface tension when melting. Surface tension is the nature of the material, can not be eliminated, but can be changed. 1.The main me...Read more -
Is The Limit Temperature of IC Chips Absolute?
Some common rules When the temperature is about 185 to 200°C (the exact value depends on the process), the increased leakage and reduced gain will make the silicon chip work unpredictably, and the accelerated spread of dopants will shorten the chip life to hundreds of hours, or in the best case, ...Read more -

What Are The Causes of PCB Board Deformation?
1. The weight of the board itself will cause the board depression deformation General reflow oven will use the chain to drive the board forward, that is, the two sides of the board as a fulcrum to support the entire board. If there are too heavy parts on the board, or the size of the board is too...Read more -
How to rationalize the layout of the PCB?
In the design, the layout is an important part. The result of the layout will directly affect the effect of wiring, so you can think of it this way, a reasonable layout is the first step in the success of PCB design. In particular, pre-layout is the process of thinking about the entire board, sig...Read more -
PCB Processing Process Requirements
PCB is mainly to power supply processing of the main board, its processing process is basically not complicated, mainly SMT machine placement, wave soldering machine welding, manual plug-in, etc., power control board in the process of SMD processing, the main process requirements are as follows. ...Read more -
How to control the wave soldering machine height to reduce dross?
In the wave soldering machine soldering stage, the PCB must be immersed in the wave will be coated with solder on the solder joint, so the height of the wave control is a very important parameter. Proper adjustment of wave height so that the wave of solder on the solder joint to increase the pres...Read more -
What is Nitrogen Reflow Oven?
Nitrogen reflow soldering is the process of filling the reflow chamber with nitrogen gas in order to block the entry of air into the reflow oven to prevent oxidation of the component feet during reflow soldering. The use of nitrogen reflow is mainly to enhance the quality of soldering, so that th...Read more -
