常見的PCB板型號有哪些？

PCB板 模型是影響價格的主要因素之一 PCB板, 以及 PCB板 不同型號的也不同. 今天, 編輯整理了一些常見的 PCB板 要與您共亯的模型.

94HB：普通紙板, 不防火.
94V0：阻燃紙板.
22F： 單面半玻璃纖維板.
CEM-1：單面玻璃纖維板.
CEM-3： 雙面半玻璃纖維板.
FR-4：雙面玻璃纖維板.

(1) 這個 grade of flame retardant properties can be divided into 94V-0/V-1型/V-2型, 94-HB
(2) Semi-cured film: 1080=0.0712mm, 2116=0.1143mm, 7628=0.1778毫米.
(3) FR4 and CEM-3 are all plates, fr4為玻璃纖維板, cem3為複合基板.
(4) Halogen-free refers to the base 材料 that does not contain halogen (fluorine, 溴, iodine and other elements), 因為溴燃燒時會產生有毒氣體, 環境保護要求.
(5) Tg is the glass transition temperature, 那就是, 熔點.
The PCB板 必須耐火, 在特定溫度下不能燃燒, 但只能軟化. The temperature point at this time is called the glass transition temperature (Tg point), 這個值與 PCB板.

常見的 PCB板 模型, NEMA. standards stipulate as follows:
FR-1:
Flame retardant copper clad phenolic paper laminate. IPC4101詳細規範編號02； Tg N/A;
FR-4:
1) Flame-retardant copper clad epoxy E glass fiber cloth laminate and its bonding sheet 材料. IPC4101 detailed specification number 21; Tg 100 degree Celsius;
2) Flame-retardant copper-clad modified or unmodified epoxy E glass fiber cloth laminate and its bonding sheet 材料. IPC4101 detailed specification number 24; Tg 150 degree Celsius~200 degree Celsius;
3) Flame-retardant copper clad epoxy/PPO玻璃布層壓板及其粘接板材. IPC4101 detailed specification number 25; Tg 150 degree Celsius~200 degree Celsius;
4) Flame-retardant copper-clad modified or unmodified epoxy glass cloth laminate and its bonding sheet 材料. IPC4101 detailed specification number 26; Tg 170 degree Celsius~220 degree Celsius;
5) Flame-retardant copper-clad epoxy E glass cloth laminate (used for catalytic addition method). IPC4101詳細規範編號82； Tg N/A.
