SMT PCB Laser Drilling Machine
Products Description
PCB drilling, or printed circuit board drilling, is the process of creating holes, slots, and other cavities into an electronic circuit board before soldering/mounting components onto it. It is typically done by using a PCB drill bit (an automated machine) that is slightly smaller than the components placed on it. The drilling is done in the same way as a regular drill bit except with a slight twist to it. The hole can be created either through electrochemical etching (chemical milling) or by mechanical means such as drilling, laser cutting, or punching. The most common method used in manufacturing today is the combination of chemical milling and electrochemical etching. Depending on how much the board’s contour is designed, a series of small holes will be drilled onto it, which will need to be filled.

The PCB drilling is a mechanical and chemical process in which the PCB gets drilled using a PCB drill bit to achieve a specific hole size, then using electrolytic etching to remove material from the hole. Since there are two different mechanical and chemical drilling processes, they are also called 2D drilling.
The types of drills used for PCB drilling are different from what you would find for normal drilling. Most people only know about regular drills being used in the drilling process, but there are also other drills present. The most commonly used drill is the twist drill which can be found in the sizes of 0.1-2.0mm and 0.3-4.0mm, as well as slotting drills that are usually found in sizes of 1.5mm and 2.5mm, as well as both various wood drills that are usually found to be wood files around 5-8cm long (of which some have been made specifically for PCB drilling). There are also twist drills used specifically for drilling PCBs as they are milled to have better stability than regular twist drills.

HGLaser, which participates in making international laser standard,has been industry leader since 47 years ago.PCB Laser Marking Machine is designed for bar codes marking, 2D codes and characters, graphics and other information on any kinds of printed circuit board. Integrated with high-performance CO2 / Fiber laser source, import high-pixel CCD camera and micron-level mobile module, PCB Laser Marking Series is competent to pre-marking automatic positioning and post-marking feedback reporting.
The self-developed software can directly connecting information system of our customer. Marking input information can not only generated automatically by software, but also be received through network. It can be integrated with SMT online operation and automatic off-board workstation.
Comparing with label and printing, laser marking can record PCB information by marking serial number and barcode for quality control of electronic product. PCB Laser Marking Machines in different types are suitable for PCB marking of large area and irregular shape board or thin plate as well as multi-marking on one-side or multi-board in high efficiency and speed.
• High-performance CO2 / Fiber laser has high-quality laser beam, small focusing spots and well-distributed power.
• The high-pixel CCD camera makes automatic positioning, identification and feedback reporting come true.
• Gantry structure and synchronous transmission guideways ensure the stable and precision performance.
• The function of automatic focusing and track width adjusting are designed to match up different production line.
