How To Layout PCB Components
The layout of components on a PCB board is to move the components to an appropriate position according to the size of components, the mutual interference between components, the thermal effect of components and the logical relationship between compone...Learn More → -

What Is An SMT Surface Mount Connector
Generally, solder cant provide high-quality mechanical support. The strength of the plug-in itself is much larger than that of surface assembly. One is because the plug-in solder has a large cross-sectional area; the other is because the lead is inser...Learn More → -

What Are The Safety Measures For PCB Welding
Since the concentration of the chemical at 20-30 cm from the soldering iron tip is much smaller than the recommended value, the correct operating posture should be maintained during soldering. The tip of the soldering iron tip should be at least 20 cm awa...Learn More → -

What Are The Common Defects In Solder Paste Silk Screen Printing
1.The solder paste collapses. The form of expression is that the solder paste pattern is not clear and the edges are not uniform or collapsed. Possible causes of this soldering defect: poor solder quality or excessive printing gap and excessive printing p...Learn More → -

Solder Characteristics In Printed Circuit Boards
When the tin-lead alloy is mutually melted at a ratio of 63:37, the temperature rises to 183 C, and the junction of solid and liquid will appear. The temperature at this point is called the eutectic temperature, which is the lowest temperature among t...Learn More → -

PCB Manufacturing Solderability Design
It needs to be coated on the surface of the PCB after the pcb board is etched, . There are two main aspects in this method: 1. Coating a solder mask on the non-soldering area of the pcb circuit board, which can prevent the solder from flowing thereby ...Learn More →
