Glass Transition Temperature is referred to as Tg, and tg150 fr4 is a designation for a particular type of epoxy glass. Normal FR4 Tg ranges from 130 to 140 degrees, moderate Tg is higher than 150 to 160 degrees, and China high TG PCB is more than 170 degrees. The performance of PCB anti-moisture heat resistance, chemical resistance, quality stability, and other properties improves as Tg increases. Tg 170°C PCB material is referred to as a China high Tg PCB. Greenstone is a China high tg pcb supplier which can provide satisfied high tg pcb. These days, computers, precision instruments, communication devices, etc., all frequently use high Tg materials.

PCBs with a copper thickness of more than 70um are called thick copper PCBs, sometimes also called thick copper PCBs. Copper thickness typically varies from 105 to 400 µm. The thicker the copper, the higher the power dissipation of the board. These thick copper plates are used for high current output and improved thermal management. Thick copper makes it possible to create boards with cross-sections for high current loads, which also facilitates heat dissipation. Greenstone is one of the China heavy copper pcb manufacturers which can provide the most professional products and services.

What is FR4? FR4 is the name of a type of epoxy glazing material. fr stands for flame retardant. 4 refers to the factors that differentiate it from other materials. FR4 means two things. The material. As a construction material, it refers to epoxy laminates reinforced with glass fibers. Used to make FR4 boards.

Evaluation. China fr4 pcb assembly is also a unit of evaluation. Epoxy laminates are classified. This classification shows the basic quality of the epoxy resin board.

GreensTone Electronics employs a dedicated, parts sourcing and procurement team to manage the logistics and procurement of PCB assembly components using a quality-controlled and time tested sourcing system that guarantees faultless electronic parts sourcing so our printed circuit board assembly services can be offered to our clients at the lowest cost in the global electronic contract manufacturing industry.

A ball grid array (BGA) is a type of surface-mount packaging (a chip carrier) used for integrated circuits. BGA packages are used to permanently mount devices such as microprocessors. A BGA can provide more interconnection pins than can be put on a dual in-line or flat package. The whole bottom surface of the device can be used, instead of just the perimeter. The traces connecting the package's leads to the wires or balls which connect the die to package are also on average shorter than with a perimeter-only type, leading to better performance at high speeds.
