Description
Technical Field
The invention relates to the technical field of ink curing, in particular to a primary curing method for printing ink.
Background
COF is an emerging IC packaging technology, but its process is compatible with the traditional FPC and IC mounting technology, so people can produce COF products with the existing equipment, the fine circuit production is accompanied with the pitch reduction of chip mounting and the increase of I/O number, the requirement for fine circuit patterns is also increased, the fine patterns with the line width and the spacing less than 50 μm are required, wherein the line width at ILB (internal lead connection) is developed from 22.5 μm in 2001 to 15 μm in 2005, and the trend is bound to continue, in this case, the circuit produced by COF is more fine; the Pitch of the COF fine circuit is thinner due to different densities of various components of the ink, the ink bleeding phenomenon during printing is caused by the thickness of Cu and the thickness of the printing ink, and according to the size method of the current COF product client, the ink bleeding range s around the device of the COF product is required to be 0.2 +/-0.2 mm, but the limit range s is required to be 0.1 +/-0.1 mm according to the type of the printing ink; therefore, the control of the range of ink bleeding is very strict, and the invention of the device for controlling ink bleeding in the initial stage is particularly important.
The control method in the prior art is that after a printing unit is printed by a screen printing, the printing ink can be conveyed to a coiling end only by conveying for a certain distance, the ink seeps out due to the static state of the printing ink and the separation of components, an air knife is additionally arranged above a buffer section at one side of a printing machine body, namely, an air blowing device is additionally arranged in front of a coiling section to blow the printing ink on the surface of a product, so that the volatilization of a medicament on the surface of the printing ink is accelerated, and the primary effect control of the ink seeping amount is realized. And thus does not work much.
