26 Years in FR4 PCB Manufacturing
FR4 is not a certain material but means a materials grade designated by NEMA (National Electrical Manufacturers Association), among which “FR” stands for flame retardant. FR4 PCBs contain many kinds of materials, most are composed of tera-function (chemical functional group) epoxy resin, woven fiberglass cloth with filler, in the PCB industry generally refer to FR4 epoxy glass cloth laminates. Because of the good electrical insulation properties, high flatness, and excellent mechanical strength, FR4 PCBs are currently the most common used circuit boards in various fields.
PS is a 26 year’s PCB supplier uses the top materials from level 1 suppliers for FR4 PCB manufacturing, quick-turn PCB delivery time reaches as fast as 24 hours.

Tg of FR4 Materials
Tg is the glass transition temperature, in other word, the melting point. When the temperature rises to a certain threshold, the FR4 PCB will change from “glass state” to “rubber state”. The temperature at this time is called Tg of that board. That is, Tg is the highest temperature at which the FR4 PCB remains rigid, boards’ mechanical and electrical properties will drop sharply when it beyond Tg temperature, which affects the service life of the product, so this value must be considered when select FR4 PCBs.
PS can provide FR4 PCB with low Tg, mid Tg and high Tg,
-Low Tg: 110~130℃ (Default)
-Mid Tg: 135~160℃
-High Tg: >=170℃
