如何结合酚类 - 成功的酚类粘结

How to bond phenolic?

与820的债券酚类

High-temperature resistant cyanoacrylates bond phenolic and allow flip chip bonding.

酚类很容易粘合,因此可以使用许多粘合剂类型(并在下面列出)。当涉及PCB时,除了粘附外,还有几个要考虑的要点。最重要的是:

  • Electrical Properties
  • Thermal Conductivity
  • Heat Resistance
  • 非腐败性质
  • 火焰阻力
  • Etc…

用一个粘合剂专家。

为了考虑杆和管性能的结构应用可能包括:

  • 冲击阻力
  • Solvent Resistance
  • Environmental Resistance

氰基丙烯酸酯:所有等级都很好。对于低气味,请选择94X产品。对于高温阻力,请选择820。

1和2组分环氧树脂also bond well. For heat cure epoxies, check the temperature rating of the phenolic to ensure you stay within its limits. ES578 offers flame resistance and good thermal conductivity as well as good electrical resistance.

Structural acrylics键酚井 - 考虑一种非腐蚀性,无甲基丙烯酸的配方,例如TA439和TA4590。bob账号客户端Permabond TA4392具有火焰电阻和良好的导热率。

紫外线可固化的粘合剂bond well, providing light can reach the bond. For coating and doing, consider UV681 and UV683.

什么是酚类?

Phenolic is a hard dense material made by applying heat and pressure to layers of paper or fabric impregnated with phenolic resin. Phenolic paper is a type of composite used for PCBs (printed circuit boards). It is also known as FR-1 or FR-2. The FR1 has a 130C rating, and FR2 has a rating of 105C. FR1 and FR2 make single-layer PCBs.

What about FR4? FR4 is not phenolic based but an epoxy based composite that is very popular for multilayer boards. FR4 is likely the most popular type.

酚和管中也可用。
