Solder Preforms are used in a variety of applications that require precise amounts of solder. Solder Preforms come in standard shapes such as squares, rectangles, washers and discs. Typical sizes range from .010" (.254mm) up to 2" (50.8mm). Smaller and larger sizes, as well as custom shapes, are also available.

A1、「預成型錫片（以下簡稱「錫片」）」使用時建議搭配錫膏(solder paste)使用，亦即在SMT製程時先印刷錫膏，再於錫膏上面放置錫片，使用上並沒有特別間距的要求，但要注意一定不能接觸到鄰近不需要焊錫的焊墊或錫膏，否則會有跨接短路的風險。在回焊 ...

Solder preforms are formed shapes of solder that are extremely uniform. Each preform consistently delivers the same volume of solder to the joint. Solder preforms can be formed into a variety of shapes and sizes to fit specific requirements. Some of the more common shapes are washers, discs, squares, rectangles, and frames.

By providing a consistent and precise solder volume, the ALPHA Exactalloy Tape and Reel preforms improve the reliability and performance of components used in PCB assembly. Selective solder volume increase for solder joint strengthening

“预成型锡片(Solder preforms)”是一种挤压成型的小锡片，可以用来局部增加锡膏印刷量，帮助因为使用钢板印刷而受限的锡膏量，用来改善焊锡的品质。

solder preform预留焊料 可以在特定的焊接工艺条件下，提供定量、定点的焊料，实现更优的焊接效果。 它应用广泛，可用于高端通信设备、LED产品、SMT组装等领域的焊接，具有提高焊接质量和可靠性、简化焊接工艺和提高生产效率、降低环境污染和健康风险等优势。

Solder preforms are pre-shaped pieces of solder that are used in electronic assembly and soldering processes. They are typically made from solder alloys, which are mixtures of metals such as tin, lead, silver, copper, and others.

COINING can customize Solder Preform geometry for any application. Our Solder Preforms are tailored based on solder volume and joint location, ensuring precise dimensions and tight tolerances for volume accuracy. COINING works with a variety of solder material and alloys chosen for an application are based on physical properties and strength.

2019年1月18日 · INDIUM: Solder preforms are the most versatile form of solder used in the widest variety of applications. They come in over 250 different alloys and countless shapes and sizes. This blog post helps you understand the basics of solder preforms.

AIM manufactures solder preforms in a wide range of alloys/melt points ranging from 60°C to 356°C. These alloys include gold-tin/gold-germanium, pure indium and indium alloys, RoHS compliant Lead-free alloys, and standard tin-lead compositions.
