201-3160 Heat Shield Kit
This kit includes tools and materials needed to protect heat sensitive area of a circuit board during rework.

201-3160 Heat Shield Kit
235-4010 Heat Shield Blanket protecting components and a connector prior to installation of a BGA component.
235-4010 Heat Shield Blanket
These are 5" x 7" sheets of fiberglass fabric, aluminum foil laminate with a pressure-sensitive adhesive backing. Heat Shield Blanket is designed to reflect 90% of the radiant heat energy. It will withstand continuous heat in the leaded and lead-free solder melt temperature range as well as short term exposure at temperatures up to 1000°F/538°C.

Heat Shield Blanket is recommended over Heat Shield Plates for more demanding heat protection. Heat Shield Blanket can be used in conjunction with Heat Shield Plates to create more robust thermal shield with a more rigid structure.

NOTE: Heat Shield Blanket has an adhesive backing and is protected with a release liner. The release liner must be removed and discarded prior to use.
201-3160 Heat Shield Kit
235-4060 Heat Shield Plate cut to shape and held in place with High Temperature Tape.
235-4060 Heat Shield Plates
These are light gauge 5" x 7" aluminum sheets used primarily when simple heat deflection is required. Heat Shield Plates are easy to size, cut, form and bond or tape into place using the High Temperature Mask or High Temperature Tape supplied in the kit.

NOTE: Aluminum is a good conductor of heat. When using Heat Shield Plate material to deflect heat leave a small space between the Heat Shield Plate and the component or area being protected to avoid direct contact transfer of heat.

115-9010 Mask, High Temperature
This product is a high temperature, quick cure, synthetic latex, peel-able solder mask supplied in syringes with dispensing needles. This mask can be used to create free form heat shielding or used to seal the edges Heat Shield Blanket or Heat Shield Plates. Product cures at room temperature in 5 minutes. Once dried, it can be peeled off after use.
