How to choose the size of reflow soldering? What temperature zone is more suitable?
Many electronics factories think that purchasing a larger reflow soldering machine can meet the general performance requirements, but it usually costs a lot of money and sacrifices the space occupied. 8 to 10 zone reflow and faster belt speeds may be the best solution in a high volume production ...Read more -
What is the difference between reflow soldering and wave soldering? Which one is better?
Today’s society is developing newer technologies every day, and these advancements can be clearly seen in the manufacture of printed circuit boards (PCBs). The design phase of a PCB consists of several steps, and among these many steps, soldering plays a vital role in determining the qualit...Read more -
How to Identify and Respond to 6 Types of PCB Fogging Coating Conformal Coating Defects
Given the variables involved in the conformal coating process (e.g. coating formulation, viscosity, substrate variation, temperature, air mixing, contamination, evaporation, humidity, etc.), coating defect issues can often arise. Let’s take a look at some common problems that can arise when...Read more -
PCB conformal paint coating thickness standard and tool usage method
Standard requirements for coating thickness of PCB conformal paint The normal coating thickness of most circuit board products is 25 to 127 microns, and the coating thickness of some products is lower. How to measure with the tool Circuit boards must be protected with the thinnest possible coatin...Read more -
IC is a key component of a printed circuit board, how to determine whether it is new or used?
1. Check the part body table If a used part has been polished, it can be viewed under a magnifying glass and there will be tiny scratches on the surface. If the surface is painted, it will look bright without the plastic texture. 2. Check the printed text High-quality producers use laser printers...Read more -
