Kapton tape for PCB manufacturing

Polyimide tape is one of the most heat-resistant tapes on the market. It shows great peak strength in a variety of high-temperature conditions, making it one of the ideal choices for applications in high-temperature environments. Most importantly, polyimide tape has excellent chemical resistance and insulating properties. It is unaffected by acids or oils and keeps electrical components at a constant temperature, which is why many industries use polyimide tape to ensure that their electronics do not ignite or fall below the desired temperature.

Kapton tape is a high-performance polyimide tape widely used in PCB (Printed Circuit Board) manufacturing due to its excellent thermal, electrical, and chemical properties. This tape can withstand high temperatures and is therefore suitable for applications that require heat resistance.

What is a PCB made of?

Typically, printed circuit boards are usually made from a non-substrate material with multiple layers of copper wire circuitry on top. Printed circuit boards can be single sided (one layer of copper), double sided (one layer of substrate with two layers of copper on each side), or multilayered (outer and inner layers of copper, alternating with layers of substrate). Printed circuit boards also typically contain adhesives and a number of components that need to be protected, such as rubberized adhesives, polyimide films, and other silicone compounds to help the board withstand high temperatures and various other high-temperature applications.

Precision: Thin and easy to cut for precise applications.
Non-Conductive: Prevents electrical shorts.
Residue-Free: Minimal adhesive residue when removed, reducing cleanup time.

Kapton tape for PCB manufacturing Application

Solder Mask Protection:

Used to mask areas of the PCB during soldering to prevent solder bridging or contamination.

Component Protection:

Protects sensitive components from heat, flux, and solder splatter during reflow or wave soldering.

Insulation:

Provides electrical insulation between conductive traces and components.

Stencil Alignment:

Used to secure solder paste stencils during the printing process.

Thermal Management:

Acts as a thermal barrier to protect components from excessive heat during assembly.

Flexible Circuit Boards:

Used in the manufacturing of flexible PCBs due to its flexibility and heat resistance.

Debugging and Rework:

Temporarily covers traces or components during debugging or rework to prevent short circuits.

SMT high-temperature protection

Suitable for SMT reflow soldering PCB board over the oven tin furnace when high-temperature protection tear off the tape without residual adhesive.

3D Printing

Suitable for 3D printing applications, affixed to the printing table for high-temperature masking, so that the product does not stick to the substrate.

Insulation wrapping

Insulating material for lithium battery motors, capacitors, transformers, coils, etc. in the electronics industry.

Paint protection

Suitable for high temperature spraying and baking paint shielding protection for metal materials, easy to peel off after high temperature spraying and baking without leaving residual adhesive.

How to Use Kapton Tape in PCB Manufacturing

Surface Preparation: Ensure the PCB surface is clean, dry, and free of dust or contaminants.
Application: Cut the tape to the required size and apply it to the desired area. Use a squeegee or similar tool to ensure proper adhesion and remove air bubbles.
Removal: Peel off gently after use. If residue remains, clean with isopropyl alcohol (IPA).
