Mid Tg laminate and prepreg like TU-662 is recommended for general use in any new projects that do not have any special requirements. It has good resistance to moisture and heat, which makes it a good choice for applications requiring long-term performance.

High Thermal Reliability

This laminate and prepreg has a high thermal reliability characteristic. The thermal conductivity can effectively improve the thermal resistance of the overall structure. This means that TU-662 can be used in a variety of environments and conditions.

UV-Block Characteristic

UV-block is an important characteristic of TU-662 laminate and prepreg. It is a measure of the material’s ability to block ultraviolet rays. If a material has a UV-block characteristic, it will not be affected by the sun’s ultraviolet rays. This can cause damage to many materials.

The UV block is an additional coating that is applied to the surface in order to prevent or reduce the amount of ultraviolet light which is harmful to the product.

AOI Compatible

AOI Compatible

AOI Compatible

This indicates that the laminate is able to be processed in an Automated Optical Inspection (AOI) system. This means that it can be inspected and passed through a machine that uses a laser to inspect the quality of the product.

This laminate and prepreg is compatible with the AOI process. This means that it can be used to produce parts that will pass inspection.

TU-662 Features

This is an excellent laminate and prepreg for manufacturing printed circuit boards. It has many great features that make it the perfect choice for this process.

Lead-Free Process Compatible

The TU-662 is a lead-free process-compatible solder paste with low melt to support soldering on the printed circuit boards and other components. This solder paste has been specially formulated for use in soldering applications. These are required to adhere to lead-free processes, according to RoHS directive. This solder paste can be used for both manual and automatic wave soldering processes.

Anti-CAF Property

The Anti-CAF property prevents a device from damaging its own circuitry. It does this by incorporating a feature that stops the device from being able to send signals when it detects damage to its own circuitry. This is a significant benefit for electronics manufacturing of printed circuit boards because it ensures that devices will continue to function as intended even after they are damaged or exposed to contaminants.

Optical Feature

The TU-662 is an optical-grade silicone that provides UV-blocking properties to printed circuit boards. It is a high-quality coating for use on the surface of PCBs. This can be applied by either spray or dip methods. The TU-662 gives excellent adhesion to the substrate and has high thermal resistance, low dielectric constant, and good aging properties.

High Interlayer Bonding Strength

This laminate and prepreg has excellent mechanical strength and can be used in many applications. It is designed for interlayer bonding. With strong adhesion to resin, high elongation, and tensile strength, as well as excellent water resistance.

It is designed to minimize the amount of resin that flows into the space between the layers. It thus provides excellent interlayer bonding strength.

Low Moisture Absorption

Low Moisture Absorption

Low Moisture Absorption

This means TU-662 will not absorb moisture from the air. This is especially important for electronics manufacturing of printed circuit boards because when the material absorbs water, it can corrode and degrade.

This is important because it ensures that the solder joints on your printed circuit boards will remain strong and reliable over time. This helps prevent corrosion and reduces the likelihood of cracks or breaks.

Fluorescence for AOI

Fluorescence is the process of absorbing light and then re-emitting it at a longer wavelength. This process is used in AOI (Automated Optical Inspection) to detect defects in printed circuit boards.

The TU-662 can detect fluorescent markings on the PCB by using a dedicated UV lamp. The UV lamp helps to identify any defects on the PCB, such as missing or extra solder joints, incorrect components, and more.

Best Thermal Resistance

PCB Thermal Resistance

Best Thermal Resistance

This is a measure of how well a material can resist heat flow. The lower the thermal resistance, the more effective the insulator becomes. This ensures that heat is not transferred from one area to another and helps to prevent overheating.

The TU-662 thermal pad is an excellent choice for printed circuit boards that need to maintain their performance in high temperatures. The pad’s thermal resistance can handle heat loads. That makes it ideal for use in applications where heat cannot be dissipated quickly enough by the underlying surface.

Superior Chemical Resistance

Chemical resistance is an important feature of a printed circuit board. It ensures that the board can withstand the environment it is installed in.

The material has high corrosion resistance and can withstand exposure to various acids, alkalis, and salts. This makes it an excellent choice for circuits that will be used in harsh environments. This material is used to provide insulation between rigid printed circuit boards and other structures such as metal cases or connectors. The material can withstand the harsh environments of typical PCBs.

FR-4 Compatible Processing Conditions
