The number of layers ranges from 2 to 20, and there is a proven track record of resin filling up to a thickness of 3.2mm!
We would like to introduce the "Through Resin Filled Circuit Board" handled by Matsuwa Sangyo Co., Ltd. This printed circuit board is mainly used for boards that mount narrow pitch BGA components (such as 0.5 to 0.3 mm pitch) and for the purpose of filling through holes (TH). After filling the holes (primary TH) that need to be resin-filled with a permanent hole-filling ink (epoxy resin), through holes (secondary TH) are formed, and it is also possible to create a cover plating on the primary TH section that has been resin-filled. 【Example of Manufacturing Specifications for Through Resin Filled Circuit Board】 ■ 12-layer through resin filled circuit board with 0.4 mm pitch BGA - Board thickness: t1.6 mm - BGA pad diameter: φ0.32 mm - Resist opening: φ0.25 mm - Resin filled TH drill: φ0.2 mm *For more details, please refer to the related links or feel free to contact us.
