Abstract
The invention provides a method and a system for printing a coating on a 3D (3-Dimensional) surface. A solder mask layer can be correctly printed on a PCB (Printed Circuit Board), or the coating is printed on a similar medium. Printing is performed according to an actual 3D outline of the printing medium through 3D scanning, thus the coating meeting the requirement of printing surface and also according with design idea is printed; defects caused by the coating directly printed on the medium deviated from a design model according to the design model are prevented, and the printing defect caused by sampling evaluation incapable of reflecting real overall condition correctly is also prevented.
Description
Technical field
The present invention relates to print the method and system of coating on 3D surface, meet the coating of design idea at 3D surface printing.
Technical background
In PCB process, while processing welding resisting layer by inkjet printing, welding resisting layer must get up outer field PCB route protection on request.
If the piling height of printable layer is not mated with the thickness of line layer, too much accumulation can cause the unnecessary waste of welding resisting layer material, and piling height can cause the protective layer thickness of circuit inadequate not; Ink droplet is printed on incorrect position, can cause various welding resisting layer defects, as too thin in welding resisting layer, the anti-pad of burn-oning.
But in the actual process of PCB, the thickness of circuit, width, position all can and PCB there is deviation between designing a model.In order to make up these difference, prior art can be by measuring several reference zones or the point of print surface, the difference between assessment reality and design, and make compensation.But the overall difference drawing by sampling and mathematical computations, this can not guarantee to be consistent with real difference, the difference that especially inhomogeneous deformation causes.Meanwhile, the assessment based on two-dimentional and compensation are nonsensical for three-dimensional difference.
Application number is 201110442660.1 Chinese invention patent, and method how to print welding resisting layer on PCB circuit is provided.This invention is to determine according to line design thickness the height that welding resisting layer is printed, can not overcome actual track thickness and design a model between the defect that causes of difference.
Application number is 201080039715.8 Chinese invention patent, and method how to print welding resisting layer on PCB is provided.This invention determines that the correct print position of welding resisting layer is the overall difference between calculating and assess PCB actual state and design according to the upper several reference zones of PCB, then compensate, and not disclose these assessments is the assessments based on three-dimensional.
