The main purpose of the present research is to reduce the junction temperature of the IC package by using a Printed Circuit Board (PCB) coated with new Photo-imageable Solder Resist (PSR) that has high thermal conductivity. The thermal conductivity of the newly developed PSR is about five ...
Liquid Photo-imageable Solder Mask Liquid Photo-imageable LPI soldermask is a liquid ink made of two component which PCB manufacturers spray-coats or silkscreen on the circuit board. This solder mask is an economical product which comprises polymers and solvents. The combination of polymers and ...
Evaluation of Solder Resist Based on Polyester P-4b with both Photoreactive Methacryloyl Groups and Alkaline Developable Carboxyl Groups The patterning property of the prepared solder resist was measured with a SEM image. The resist solution composed from the mixture of main resin (P-4b with 55% ...

Composition of Photo-Imageable Solder Resist Mask and Demand Properties A recent trend of increasing circuit density and functions of PCB diversifies demands for a solder resist mask. When the solder resist mask was introduced,... INAGAKI,Shoji - 《Gomu》 被引量: 0发表: 2006年 Microbiome and ...
imageable electro-phoretically deposited organic resin is used to provide, on an already patterned surface, an additional resist pattern which selectively exposes areas on which the solderable metal coating is to be provided and in which the resist serves also as an etch resist for metal areas ...
Here, we report guided orientation of silver nanowires (AgNWs) in extruded patterns with photo-curable 3D printing technology. A printable conductive composite material composed of polymer matrix and silver nanowires shows significantly varied electrical
basic resist release solutions, solvents for an oriented film coating and the like), (4) to have transparency in the visible light region without cloudiness and turbidness, and (5) to show excellent adhesion not only to the multicolor image layer, but also to the substrate, because the prote...
1. A method for removing a epoxy acrylic copolymer photoimagable solder mask of a negative resist simultaneously from the insulating laminate and conductive metal braces of a printed circuit board comprising the steps of: (a) contacting the permanent photoimagable solder mask on the insulating lami...
6) liquid photo-imageable solder resists 液态光成像阻焊剂 1. This article summarized the kinds of liquid photo- imageable solder resists and its components; it is also dis-cussed the influence on solder masks properties by process and control; moreover, the developments of solder resists is me...
