Polyimide Circuit Board

Withstands multiple cycles of harsh condition washes for printed circuit boards and electronic component preprocess labeling.

Polyimide circuit board.

It is known for its good thermal stability and chemical resistance values. The thermal conductivity of this material is far better than that of the fr4 material. Resists high temperatures up to 572 f 300 c. High tg 250 c results in low overall processing and minimizes risk of latent pth defects in service.

Polyimide is a flexible polymeric film often used as a substrate for printed circuit boards. This is particularly true with the increasing popularity of electronic and smart cars where a polyimide circuit board may be the only practical choice. Polyimide occurs naturally in nature but can also be prepared synthetically. Polyimide material is most commonly used in the flexible printed circuit boards.

It provides good mechanical strength and heat resistance to the pcb. 33n is a flame retardant ul 94 vo polyimide laminate and prepreg system where the excellent high performance properties of polyimide need to be combined with flame retardance. If you are planning to use your pcb in a high heat setting an fr4 board is probably not the best choice. Flexible and rigid flex circuit boards are typically made out of polyimide and are generally preferred in applications where mobility and frequency of use are a primary concern.

The polyimides that are used in the flex pcbs are generally imide monomer polyimides. This is a broader category that includes many consumer focused goods that require circuit boards and. Polyimides also found in flexible printed circuit boards are imide monomer polyimides. Polyimide isola offers a product line of polyimide based no flow prepreg materials for high temperature printed circuit applications these products consist of a flame resistant polyimide resin system suitable for military commercial or industrial electronic applications requiring superior performance and the utmost in thermal properties.

High temperature polyimide b 727 withstands wave solder environments and multiple harsh washes for printed circuit board and electronic component preprocess labeling. The military or defense pcbs use polyimide as a substrate. Amber high temperature polyimide with an ultra durable adhesive withstands the extreme wash protocol and cleaning chemicals used in printed circuit board manufacturing. Consumer electronics are not the same thing as computer electronics.

Tg greater than 250 c.
