High Tg Circuit Boards

What is High Tg Circuit Boards (High TG printed circuit board) ?

Tg means Glass Transition Temperature.FR4 is a code name for a grade of Epoxy Glass material. The higher Tg, the better performance of PCB heat resistance, moisture resistance, chemical resistance, stability, and other characteristics. General fr4 Tg is 130-140 centigrade, moderate Tg is greater than 150-160 centigrade, High-Tg is greater than 170 degrees.

As usual, made with Tg ≥ 170℃ PCB material, which is called high Tg printed circuit board. With the rapid development of the electronics industry, high Tg material is widely used in computer, communication equipment, precise apparatus and instrument and etc.

FR4 material can often provide the best solution

The glass transition temperature of PCB, referred to as "Tg", indicates the point at which the PCB material will begin to transform. If the operating temperature exceeds the designated Tg value, the board will begin to change from a solid to a liquid state, which is likely to have an adverse effect on its ability to function.

Standard PCBs are manufactured with materials offering a TG value of 140°C, which can withstand an operating temperate of 110°C. While this may not be suitable for extreme-temperature processes that are commonplace in applications such as automotive, industrial or high-temperature electronics. In these situations, a PCB made from FR-4 material can often provide the best solution.

What Is FR4?

FR-4 is a grade designation for flame-retardant fiberglass reinforced epoxy material. Thus, FR-4 PCB offers a much greater level of resistance to heat than a standard PCB. FR-4 circuit boards are divided into four classifications that are determined by the number of copper trace layers found in the material:

• Single-sided PCB / Single-layer PCB
• Double-sided PCB / Double-layer PCB
• Four or more than 10 layers PCB / Multilayer PCB

PCB Shipment

JHY PCB offers flexible shipping methods for our customers, you may choose from one of the methods below. 

Shipping Process
After production and testing, your PCB orders will be sent to our shipping department. As the quick turn PCB manufacturer, JHY PCB shipping department will ship your PCB quickly without any pending.

JHY PCB 's Packing Way

• Use one professional PCB vacuum bag, with desiccant inside. Vacuum compressed totally.
• Paste label and RoHs mark. Use second vacuum bag to protect boards again, vacuum compressed, make sure no exception.
• Microsection report and Tin testing board are put together with PCB in cartons.COC (Certificate of Conformity)  will be sent to customer by email in PDF.
• Several layers of thick EPE(Expand aple poly ephylene) are filled fully in gaps between PCBs and cartons. Thickness of 1 layer EPE is 10mm.
• Neutral Packing is adopted if no special requirements. Strong and thick cartons(Thickness:10mm,7 layers). Different sizes of cartons are designed to meet demand of different PCB size. All package are within weight limit of cartons. For mass production order, no exceed 21kg per carton normally.
• All cartons sealed with strong adhesive tape should be sealed twice so as to make them more durable.
• Solid PP/PET strapping is used outside of cartons. 
• Shipping mark, fragile mark and postcode label are all pasted clearly.

Whatever we do or whatever we think of is to make sure boards are shipped to customer safely and quickly.

How to ship your PCB?

• Firstly, JHY PCB shipping department will print order address and invoice.
