High-Tg PCB
PCBSINO PCB fabrication for High tg PCB, we can use Shegnyi and ITEQ material to meet the customers' requirement. Most PCBs are constructed with material that has a Tg temparature value of 135C. This PCB can operate at temperatures of up to 110°C Tg stands for glass transition temperature and indicates the temperature at which the PCB material starts to transform. If the operating temperature higher than the designed Tg value of the PCB base material, the board will change from a solid to a liquid state and this will affect its function and performance. high-Tg PCB are suitable for applications of product that will involve extreme temperature variations, such as automobile electronics, industry electronics, and high-temperature electronics. PCBWell offers high-Tg PCBs that have a Tg value of up to Tg 175.

What is high Tg PCB?

What is high Tg PCB?
there are many customers request to manufacture PCB with high Tg, so what is high Tg PCB?
Normally high Tg refers to high heat resistance in PCB raw material, the standard Tg for copper clad laminate is between 130 – 140℃, High Tg is generally greater than 170℃, and middle Tg is generally greater than 150℃. if PCB with Tg≥170℃, we call it high Tg PCB.
now more and more industry products, especially for the computer as the representative of electronic products, developing toward the more and more better performance, high multilayer requires PCB substrate material with higher heat resistance to ensure high reliability. also, SMT soldering develope to a higher level, CMT with high density pcb assembly technology, the PCB manufacturing with small hole size, fine lines and thin thickness are more and more inseparable from the support of high heat resistance.
TG means Glass Transition Temperature Temperatures that are associated with long term operations must be considered in the manufactured of printed circuit boards that will be exposed to high thermal loads.. The function of a circuit board will be affected if its temperature exceeds the designated Tg value.
PCBSINO providing many type high TG PCB products to a variety of industries since 1998 from telecommunications to consumer electronics, aerospace, automotive and more. We have also provided high TG PCB products to Fortune 500 companies.
All of our printed circuit boards are tested and certified with ISO9001, TS16949 and UL.
Do I have to use an FR4 material with a high Tg?

Do I have to use an FR4 material with a high Tg?
just for lead-free soldering?
PCBSINO answer: not necessarily. There are many factors to be taken into account, e.g. how many layers, the thickness of the PCB and also a good understanding of the assembly process (number of soldering cycles, time above 260 degrees, etc.). Some research has shown that a material with a “standard” Tg value has even performed better than some materials with a higher Tg value. Note that even with “leaded” soldering the Tg value is exceeded.
most importance is how the material behaves at temperatures above the Tg value (post Tg), so knowing the temperature profiles of the PCB will help you evaluate the necessary performance of the PCB boards.
High Tg PCB application:
If working temperature of your product is higher than normal (130-140C), then have to use high Tg material which is > 170C. and popular PCB high value are 170C, 175C, and 180C. Normally the PCB Tg value should be at least 10-20C higher than working temperature of product. If you 130TG board, working temperature will be lower than 110C; if use 170 high TG board, then maximum working temperature should be lower than 150C.
Here are some popular High Tg board raw material in market:
S1170 & S1000-2: SYL (Shengyi Technology);
FR406, FR408, IS410 & DS370HR: Isola
HR-01 & HR-02: Mica-AVA;
MCL-E-679: Hitachi;
N4000-6 & N4000-11: Nelco
of cause there're a lot of different hi-tg material not listed yet, different country, different company prefer using different material. Please view datasheet for each of them to choose most suitable material for you. normally PCBSINO will use ITEQ High TG PCB material.
