Method for manufacturing water resistant printed circuit board
A method for manufacturing a water resistant substrate comprises a first step of providing a substrate. The method proceeds with a step of populating at least one component onto the substrate. Next, the method includes a step of cleaning the substrate including the at least one component to form a cleaned substrate. Then, the method proceeds with depositing a multi-layered water resistant coating onto the cleaned substrate.
Modified silicone compound, and thermosetting resin composition, prepreg, laminate plate and printed wiring board using same
There are provided a modified silicone compound prepared by reacting: (A) a siloxane diamine represented by the general formula (1); (B) a maleimide compound with at least two N-substituted maleimide groups in the molecular structure; and (C) an amine compound with an acidic substituent; and also provided a thermosetting resin composition, a prepreg, a laminated plate, and a printed wiring board that are formed by using this compound. The multi-layered printed wiring board produced by using the laminated plate formed by using the prepreg obtained from the modified silicone compound and the thermosetting resin composition of the present invention through laminate molding has an excellent glass transition temperature, coefficient of thermal expansion, copper foil adhesion, hygroscopicity, hygroscopic solder heat resistance, and copper-stuck solder heat resistance. Therefore, the multi-layered printed wiring board is useful as a highly integrated semiconductor package and a printed wiring board for an electronic device. ##STR00001##
ELECTRONIC MODULE FOR MEDICAL DEVICE
An electronic module for a medical device such as an inhaler is disclosed, the electronic module comprising a printed circuit board, and a damper configured to dampen energy transfer to and/or from a battery when a battery is connected to the electronic module and the electronic module is exposed to mechanical shock.
Room temperature-vulcanizing silane-containing resin composition and mounting circuit substrate
Room temperature-vulcanizing silane-containing resin compositions are described, containing: (A) 100 parts by mass of a silane-modified polybutadiene compound represented by formula (1) ##STR00001##
(B) 0.5 to 20 parts by mass of a hydrolyzable organosilane compound having in each molecule an average of at least two silicon atom-bonded hydrolyzable groups, and/or the partial hydrolysis condensate of this hydrolyzable organosilane compound; and (C) 0.1 to 10 parts by mass of a curing catalyst. This room temperature-vulcanizing silane-containing resin composition is suitable for application as a coating agent composition and in particular as, e.g., a coating agent for electrical and electronic components and substrates therefor, and a sealant for liquid crystal display elements. The room temperature-vulcanizing silane-containing resin composition provides a gas permeation-resistant coating film (cured material) and is useful as a coating agent that exhibits a corrosion-inhibiting capability versus corrosive gases.
Stretchable touchscreen, method for manufacturing the same, and display device using the same
Disclosed are a stretchable touchscreen, a method for manufacturing the same and a display device including the same. After using a material having a high elastic restoring force as a substrate and determining regions where touch electrodes are formed by defining grooves thereon, touch electrodes are formed by filling the grooves with nanowires. Accordingly, it is possible to maintain elastic restoring force of the substrate and electrical connection between wires of nanowires, so that the touch electrode neither breaks nor factures despite being stretched any direction, and reliable stretchable touchscreens can be provided due to no resistance increase.
