Dependable and Reliable Fabricator of VT-901 l PCBTok

VT-901 is one of the best PCBs in the market today. It is a highly durable type of board that can withstand high temperatures, as well as cold temperatures. It has excellent thermal conductivity, which means that it will not break down due to heat damage or freezing cold temperatures.

The boards are also resistant to moisture, so they will not corrode if exposed to water or moisture for long periods of time. This makes them ideal for use in industrial settings where there may be some risk of exposure to moisture or other environmental factors that could cause damage to electronic components such as transistors or resistors.

The boards are also very lightweight, which makes them easy to transport from place to place without having to worry about damaging them during transit because they’re too heavy for their own good! The low weight means that you don’t have to worry about adding extra weight onto your shipment by shipping out more products than necessary.

PCBTok is one of the leading manufacturers, supplying the best quality VT-901 to our clients. We have been able to gain the trust of our clients through our high-quality products and services. PCBTok strives to provide the best products at affordable prices for all our customers.

VT-901 Low Z-Axis CTE

The VT-901 Low Z-Axis CTE of circuit board is a measure of how much the board shrinks along its z-axis (the axis perpendicular to the surface of the board). The smaller the number, the less it shrinks. This is important because when you’re trying to solder something onto a circuit board, it’s helpful if that thing doesn’t shrink away from you.

VT-901 is a low Z-axis coefficient of thermal expansion material for SMT testing and manufacturing applications. It provides high thermal conductivity, low creep and stress relaxation, good resistance to solder reflow temperatures, and excellent dielectric properties.
