Description
Technical field
The present invention relates to wiring board production technical field, particularly belong to the wiring board coating agent that a kind of electrical insulating property is excellent.
Background technology
Wiring board (metal circuit board) with the metallic plate of aluminium sheet etc. as matrix, has exothermicity and mechanical strength,
And weight member can be carried, increase the feature of current capacity.This metal circuit board is implemented the circuit such as etch processes add
In man-hour, use the medicament of bronsted lowry acids and bases bronsted lowry.In order to prevent the erosion of the end face part of metal circuit board caused due to these medicaments, with
Toward being to paste, at the end face part of metal circuit board, the adhesive tape preventing corroding by manual work, it is being etched process grade
After, from described metal circuit board, take erosion off by manual work and prevent from using adhesive tape.This method, the most still described in prevent from invading
Erosion adhesive tape costly, and owing to being that manual work is so cost of labor is high.And the problem that also working performance is low.
Additionally, on the installation wiring board of electronic unit, in addition to above-mentioned metal circuit board, be also used extensively by comprising
The printed substrate (i.e. glass epoxide wiring board) of glass epoxide parts.Glass epoxide wiring board is at overlapping glass fabric
Above formed containing epoxy resin dipping.Therefore, when cutting off glass epoxide wiring board, produce by epoxy resin or glass fibre group
The trickle dust become.These trickle dust likely cause asking of degradation under the loose contact of wiring board circuit and quality
Topic.Therefore, it is necessary to remove the dust produced when cutting off and manufacturing wiring board.
When wiring board self is the thinnest, in order to not produce when stacking at the wiring board that will be formed with frame shape film
Raw volume increases and bending, it is necessary to the thickness making film is the thinnest.In addition in order to make the wiring board stacked easily use, film with
Fissility between film must be good.Even and then thin film, it is necessary to have in circuit fabrication use acid and
The sufficient drug resistance of alkali.But, meet simultaneously and be able to easily form thin homogeneous film, the film after solidification and painting
Fissility between film is good, and the wiring board coating agent of these characteristics of drug resistance excellence does not the most develop.
Summary of the invention
For the problems referred to above, it is an object of the invention to provide the wiring board coating agent that a kind of electrical insulating property is excellent.
The technical solution used in the present invention is as follows:
The wiring board coating agent that a kind of electrical insulating property is excellent, it is made up of the raw material of following parts by weight: carbamic acid
