Abstract: An electronic component packaging structure includes a circuit board, electronic components mounted on the circuit board and a moisture-proof coating layer covering the electronic components. The moisture-proof coating layer is constituted from a polymer material coating having at least two layers of a lower layer and an upper layer, and the polymer material forming the lower layer has higher swelling property and/or solubility to a repairing solvent that is selected from among hydrocarbon-based solvents than the polymer material forming the upper layer.

Abstract: PROBLEM TO BE SOLVED: To provide an applicator that adds a conformal coating to an electrical composition.
SOLUTION: The coating system employs the applicator having a cylinder with a needle valve attached. A controller has a timer that supplies a series of electric pulses to a solenoid. The solenoid applies pressurized air to a cylinder piston, thereby opening the needle valve, and this allows a coating material to pass through the needle valve. The needle valve is closed over a retention time between the pulses, and the coating material is released from a dispensation needle in response to the closure of the needle valve.

解决方案：涂层系统采用具有附接有针阀的圆筒的涂布器。 控制器具有向螺线管提供一系列电脉冲的定时器。 螺线管将加压空气施加到气缸活塞，从而打开针阀，并且这允许涂层材料通过针阀。 针阀在脉冲之间的保持时间被关闭，并且涂层材料响应于针阀的关闭而从分注针释放。 版权所有（C）2008，JPO＆INPIT
