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 alloy composition is best for solder paste used in LED strips?

Fitech, a renowned enterprise in microelectronics and semiconductor packaging materials, demonstrates significant value in LED strip soldering through its solder paste products, leveraging technological advantages and customization capabilities.

Can leaded solder paste and lead-free solder paste be used together?

Properly reheating and mixing lead-free solder paste is a critical step in ensuring soldering quality, requiring attention to uniformity while preventing oxidation and bubble formation. Below are detailed steps and precautions:

Reflow Soldering with Nitrogen Protection

In the process of lead-free reflow soldering, many companies are concerned about one question, that is, whether the oxygen concentration in the reflow oven will rise? What circumstances need to use N2 to protect the soldering method to reduce the oxygen concentration in the reflow oven?

How to Properly Reheat and Stir Lead-Free Solder Paste?

Properly reheating and mixing lead-free solder paste is a critical step in ensuring soldering quality, requiring attention to uniformity while preventing oxidation and bubble formation. Below are detailed steps and precautions:

Comparison of Advantages and Disadvantages Between ACF (Conductive Adhesive) and Solder Paste in Micro-Assembly

In the field of micro-assembly, ACF (conductive adhesive) and solder paste serve as two core interconnect materials. Their comparative advantages and disadvantages must be comprehensively analyzed across dimensions such as electrical conductivity, process adaptability.

Common PCB solderability inspection methods

PCB solderability inspection method refers to the use of certain methods and standards to evaluate the solderability of the pads or components on the PCB, that is, the wettability and interfacial reactivity between the solder and the solder.

Pad surface treatment in microelectronics and semiconductor packaging

In microelectronics and semiconductor packaging, the most basic purpose of pad surface treatment is to ensure good solderability and conductivity of the pads. Since copper tends to exist as oxide in air and is unlikely to remain as pristine copper for long, other treatments are required for copper.
