PCB material selection criteria

  PCB material selection criteria(图1)

  Obviously, the cost of the base material and the laminated material varies greatly. However, it is worthwhile to choose the right material from the beginning, rather than suffer the humiliation of expensive PCB failure.

  The following are general recommendations that can be used as a starting point for selecting materials for specific substrate/laminate applications:

  LFR-4 is widely used in standard boards. Its Tg point is 135 ℃. It also has a high Tg version (150-210 ˚ C) , making it suitable for high-density applications.

  LCEM-1, CEM-2 and CEM-3 can also work well in high-density applications. Tg of CEM-1 is 122 ˚ C. Tg of CEM-2 is 125 ˚ C. Tg of CEM-3 is 125 ˚ C。

  L For the base material, the Tg of RF-35 is 130 ˚ C. This makes it a candidate material for high-density applications.

  L Tg of Teflon (well-known in cookers) is 160 ˚ It may be a good choice in high frequency, microwave and high-power boards.

  L For high frequency, high power and microwave applications, PTFE can provide a substrate with a Tg of 240-280 ° C.

  L Under the conditions of high power, high frequency and microwave, the Tg of polyimide as the base material is 250 ˚ C or higher. Polyimide substrate is the first choice for flexible circuits because FR4 substrate is very solid. In addition to flexibility, polyimide also has high temperature resistance, but is more expensive than FR4.
