What causes solder paste to remain in the heat sink holes?

Failure to thoroughly clean solder paste from the heat dissipation holes may be caused by various factors, including the cleaning process, material properties, equipment operation, or design flaws. The following are the specific causes and analysis:

What is the difference between solder adhesive (epoxy solder paste) and solder paste?

Failure to thoroughly clean solder paste from the heat dissipation holes may be caused by various factors, including the cleaning process, material properties, equipment operation, or design flaws. The following are the specific causes and analysis:

How can the risk of the popcorn effect be reduced through solder paste process control?

The following solder paste process control measures can effectively reduce the risk of the "popcorn effect":

Reduce Soft Error Rate of Microelectronic Packaging  with Low Alpha Particle Solder Paste

A soft error is a temporary failure of a device caused by the effects of radiation on silicon integrated circuits (Si ICs).

Causes and mitigation measures of voids during soldering

Transient liquid phase (TLP) bonding is a common bonding technique in high-temperature electronic devices, especially in power device packaging. TLP bonding can be carried out at lower temperatures and can remain stable at higher temperatures.

Nano-Additives Reduces Tin Whiskers in Solder Pastes

Lead-free solder pastes are soldering materials that are most commonly used by packaging manufacturers and can be used for chip soldering and other purposes. One of the most common lead-free solder pastes is the SnAgCu series, including SAC0307, SAC305 and etc.

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.
