How Should Flux Residue Be Cleaned?

Flux residue is common after electronic soldering. If not removed promptly, it can cause short circuits, corrosion, or reduced insulation performance. The cleaning method should be selected according to the residue type, component sensitivity, and production volume.

Halogenated vs. Halogen-Free Solder Paste

Halogenated and halogen-free solder pastes differ significantly in composition, soldering performance, environmental impact, cost, and application. The details are as follows:

What are the Requirements for Lead-Free Solder Pastes from an Industrial Application Point of View?

At present, there is no universally recognized set of specifications for lead-free solder pastes. From the perspective of industrial application, the following basic technologies and application requirements of lead-free solder pastes are summarized:

How to Reduce the Formation of Solder Balls

There are solder balls with sizes about 0.2mm~0.4mm, or some exceed this range, which is mostly concentrated around chip RC components. The existence of solder balls not only affects the appearance of electronic products but also brings hidden dangers to product quality.

Why Does the Stencil Determine Whether a Solder Paste Is Good?

The stencil directly determines solder-paste printing quality and therefore affects soldering performance, making it a key factor in evaluating solder-paste quality. The specific reasons are as follows:

MOSFET Solder Selection Guide

In MOSFET applications, solder selection should be based on four core principles: temperature compatibility, performance balance, process compatibility, and reliability and compliance.

A Brief Discussion of EDA Packaging

Electronic design automation (EDA) packaging can be approached through the following steps:

What Are the Requirements for Solder Paste in DSP Packaging?

In DSP (digital signal processor) packaging, solder paste must meet three core requirements: ultra-fine-pitch printing, high-reliability soldering, and environmentally friendly cleaning. The specific technical parameters and performance standards are as follows:
