Common PCBA cleaning solution

After soldering, PCBAs need to be cleaned to remove solder dross, flux, dust and other contaminants from the board to improve its reliability and performance. Current PCBA cleaning solutions are in full bloom, each cleaning solution in different application scenarios to show the unique advantages.

How can SPI data be used to adjust solder paste printing parameters in real time?

Real-time adjustments to solder paste printing parameters based on SPI (Solder Paste Inspection) data can be achieved by establishing a closed-loop "inspection-analysis-adjustment" system.

A Brief Discussion on the Standard Viscosity Range for Lead-Free Solder Paste

The standard viscosity range for lead-free solder paste is typically 80–250 Pa·s (or 80,000–250,000 cP), but specific values must be adjusted based on the printing process, equipment, and product requirements. The following is a detailed analysis:

Ultrasonic-Assisted Bonding in Si/Cu Solder Joint

Silicon is a common crystal material with a low coefficient of thermal expansion in modern microelectronics. It is widely used in advanced packaging fields such as power devices and 3D packaging. However, as the packaging density increases.

Classification and selection of wave soldering flux

Wave Soldering is a common PCB soldering technique in which electronic components and boards (pre-applied flux in the soldered area of the board) are placed on a wave of melted solder to make a soldered connection.

What fields are leaded solder pastes suitable for?
