PCB Technical - Types, advantages and disadvantages of PCB splitter

PCB splitter is also called circuit board splitter, which is widely used in electronic PCB product manufacturing. Early splitting machines used manual manual splitting, which was low in efficiency and caused great damage to the substrate. Some boards even had components inserted. Therefore, after the development of mechanization, this processing method was subsequently eliminated.

With the advancement of science and technology, the method of PCB splitting is becoming more and more intelligent, efficient and precise. Of course, the cost has also increased, and the needs and requirements of customers have also increased. How can it stand out under the demand of modern production? For PCB sub-board processing companies, it is imperative to keep pace with the times.

PCB sub-board

The common PCB splitters are laser splitter, curve splitter, knife splitter, guillotine splitter, stamping splitter, hand-push splitter, milling cutter splitter .

Laser splitter is an emerging process. With the development of laser technology, there are more and more applications of laser technology in the field of electronic manufacturing, and the application in PCB splitter is one of them.

, According to the demand, different lasers are used. At present, there are UV lasers, CO2 lasers, green lasers and picosecond lasers. Naturally, the prices are also very different. In terms of overall cost performance, UV lasers and green lasers are currently the mainstream.

The thickness of the PCB sub-board of the ultraviolet laser cutting machine is relatively low, generally not more than 1mm. The green light is mainly high power, and the laser sub-board is carried out for the PCB of 1mm or more.

The biggest advantage of the laser dividing machine is the cutting efficiency and cutting effect. The cutting edge has no carbonization and no burrs. And it has the function of adsorption, so it is dust-free and smoke-free. The laser uses a non-contact processing method, which has little thermal influence, will not damage the substrate or the substrate of the active device, and is stress-free. It adopts CCD positioning, computer control automatic cutting, and can also realize the function of automatic loading and unloading. Maximize equipment production efficiency and save labor costs.

Of course, the shortcomings of the laser sub-board machine are also very obvious, the price is expensive, the price of the UV laser PCB sub-board machine of Top Yin Optoelectronics in September 2016 was the latest quotation of 400,000-800,000 (depending on the accessories and laser power). This is very high for the initial investment cost, but fortunately, the current PCB laser splitter of Top Yin Optoelectronics can be paid in installments, which is also the pressure of the initial investment cost.

The defects of the curved board splitter, the knife splitter, the guillotine splitter, the stamping splitter, the hand push splitter, and the milling cutter splitter are their defects. They are all contact processing methods, which will cause stress and damage the substrate. There are burrs on the cut edges, and a large amount of dust will be generated, which is not conducive to the development needs of sustainability and environmental protection.

Of course, the input cost of these models is relatively low. But generally speaking, you need to decide which equipment is the most ideal according to your own needs. For example, if the processing volume is only to meet a small part of your own production needs, then there is no need to buy high-quality equipment, you can spend more time and slowly push the splitter, but if there is a high-quality demand and For mass production, laser splitter may also be a good choice.
