Electronic Design - Inkjet printing technology in PCB copy board design

The inkjet printing technology in PCB copy board design is introduced as follows

From the current and future application and development prospects, the application of inkjet printing technology in THE PCB is mainly reflected in the following three aspects: (i) Application in graphics transfer;

The application of inkjet printing in graphics transmission.

The digital inkjet printer directly prints the corrosion inhibitor on the inner layer of the "board", and after UV curing, it can be etched to obtain the inner layer route pattern. In this way, not only eliminates the production process and equipment of perilla photographic film, but also avoids the exposure and development process and equipment, thereby saving space and space, greatly reducing material consumption, shortening the production cycle of products, and reducing the environmental pollution. And reduce costs. At the same time, the most important thing is to timely improve the position of the graphics and the precision between layers, which is extremely beneficial for improving the quality of multi-layer PCB boards and improving the product qualification rate.

It is the same as laser direct imaging (LDI), which can shorten the PCB production process and improve product quality. It is an important reform and advancement in PCB industry technology. It is superior to laser direct imaging (LDI) technology, avoiding the development process and equipment, and reducing the cost of production.

Using digital inkjet printing graphics transfer technology, its processing technology is the least, the equipment used is the least, the material is used the least, the production cycle is the shortest, and of course, the environmental pollution and cost are also the lowest!

However, judging from the current initial applications in the PCB industry, most inkjet printers (such as MicroCraft's MJ6151 series inkjet printers) have a jet resolution of 300dpi-600dpi, a minimum jet drop of 30 liters, and a line width of 80 m-150 m, which can only meet the general linear density requirements. In order to obtain a smaller line width, it is necessary to produce a smaller number of jetted droplets, higher nozzle resolution, such as 1200dpi-2400dpi jetting resolution, 3 to 6 leather liters of the smallest jetted ink droplets, the width can reach 5 m- 20 m, and the spray ink volume is at least 1 leather to 3 leather liters, then the line width can reach between 2 m-3 mm.

Of course, by changing the corrosion-resistant ink to welding ink or character ink, etc., inkjet printing layer or inkjet printing characters can be realized.

A promising PCB factory should have a long-term low profile, high efficiency, low cost, and high success rate to provide full technical support and complete solutions for project development in various industries, mainly involving circuit board copy board, PCB copy board, SMT, PCB proofing and other services, while providing component procurement and replacement according to customer needs, to be a professional PCB service provider.
