1. Introduction to the pad printing process. Pad printing is an indirect printing technology with a recessable rubber head. By making a specific steel plate pattern, the printing technology uses the rubber head to transfer the etching pattern content to the product. It has now become a printing technology for various object surfaces. A major method of printing and decoration.Principle: The process is very simple. First, the designed pattern is etched on the printing plate, the etching plate is coated with ink, and then most of the ink is transferred to the printed object through the silicone head.Main production problems and solutions: 1. Pad printing font burrs: After pad printing, small feather-like burrs appear on the edges of the fonts, making the fonts enlarged; the ink is too thin and does not dry quickly enough; the humidity is too high; solutions: A.Reduce the amount of ink thinner used; make the ink dry faster; B.The rubber head is equipped with a hot air blowing device; C.Reduce the humidity in the workshop and reduce the etching depth of the steel plate; 2. Deformation of the pad printing pattern: Graphic distortion and deformation appear on the surface of the pad printed product, mostly in the pad printing area.

1. Dimensional accuracy: Dimensional accuracy refers to the degree of difference between the actual size of the printed pattern or component and the designed size.In screen printing, dimensional accuracy refers to the deviation between the actual size and the designed size of the printed pattern, text or component.This deviation is usually within a specific range. For example, if the design size is a 10mm x 10mm square, then the printed square may have a slight size deviation, but it is within an acceptable range.

Customer Demand-oriented, CCD Visual Alignment To Upgrade

In the thick film printing process of electronic components, the CCD visual alignment system can automatically correct deviations, effectively control errors caused by manual feeding, and improve the yield rate in mass production. It is widely used in high-precision thick film printing.However, due to the complexity of operation and debugging, the requirements for skilled workers are relatively high during production and use.Recently, many old customers have asked whether the operation difficulty can be simplified and the printing accuracy can be improved when they repurchase.In response to these problems, in 2023, we visited a number of customer companies to understand the actual production needs, organized the company's technical team to conduct multiple discussions on the alignment system, and arranged for technical personnel to conduct multiple technical communications with customers.In the end, we ignored the cost investment and cooperated with CCD vision system manufacturers to conduct a large-scale upgrade of the existing software and introduced a new CCD vision alignment system.Introduction to the traditional alignment method: manually align the product with the screen position, then align the visual lens on the product to capture the MARK point
