Flexible Printing Circuit Board Small Batch Production Cutting Equipment - FPC Laser Cutting Machine

Flexible printed circuit board sample production is the first step in mass production, in the FPC shape cutting, window drilling part, more and more manufacturers choose the industry FPC laser cutting machine. In the sample production stage, compared to punching, laser cutting the advantages are more obvious. 
FPC laser cutting machine has obvious advantages for small batch production and sample of punching, shape cutting. FPC laser cutting machine use 355 nm nanosecond UV laser cutting, high precision, smooth edges without burr glue phenomenon, picosecond laser effect is better. For the customer's small batch production changes, only need to re-set on the computer, without additional adjustment equipment, shorten the production period. 
In the production of FPC flexible circuit board, the factory needs to be based on flexible board batch, customer requirements and other information to select technology and equipment, manage shipping cycle and cost.

Laser Cutting Machine Requirements for Processing Area

Laser cutting machine has requirements for processing areas. Generally speaking, the ground should be flat. The ground’s flat level directly affects the precision and speed of processing.Secondly, its processing areas generally are not allowed to have too much dust. Excessive amount of dust will not only affect the operator body and visibility. Laser cutting machine equipment space requirements to ensure the smokeless dust-free. In terms of temperature, general requirement is to load the air conditioning, because of the laser cutting machine in the process of processing work, especially in high power laser cutting machine, the high heat go out from the body. To the continuation of machining process and laser cutting machine, there must be a stable indoor temperature. Finally, laser cutting machine work is strict with the quality of the water cooling circulating water, requires the use of pure water, deionized water or distilled water, such as water. Pay attention that it can not use tap water, mineral water containing high metal ions or other minerals such as water, the water quality of laser cutting machine temperature cooling is of great influence.

Causes of Non - Round Punching of Laser Hole Checker

Many people know the advantages of laser drilling machine, the use of laser hole will be very simple and easy to use, then in fact the hole is not as we imagine the same. Because in the drilling time, vertical degree is not enough, hanging slag, jagged the situation, let us talk about the reasons for these circumstances.
1.The hole diameter is too small
The larger the diameter of the hole is the easier it is to cut, if too small holes will appear irregular hole.
2.Cut laser drilling machine manufacturing process is bad
Immature production process will make the screw or the precision of the rail is not enough, so that the accuracy of cutting machine can not meet the specified requirements.
3.Use gas mismatch or air pressure too large or too small
When punching, choose the gas material that matches the material to make the punch better. Also pay attention to the choice of air pressure.
4.Laser type
For fine perforations such as FPC above micron-scale drilling, priority is given to the use of UV lasers instead of CO2 or fiber lasers.

Why Do Not Use CO2 Laser Cutting Machine to Cut Metal?

CO2 laser cutting machine, also known as non-metallic laser cutting machine, dedicated to non-metallic materials cutting. if you must use CO2 laser cutting machine can cut the metal, is it feasible? The answer is yes, CO2 laser cutting machine can indeed cut the metal, but why is the metal cutting is usually used fiber laser cutting machine? Let us see.
There are three kinds of energy for laser processing: 
Reflection: the reflection of the material on the laser is generally not conducive to eliminate the material, such as CO2 processing copper foil, it is necessary to brown or black copper foil, reducing the reflectivity.
Transformation: conversion refers to the process of processing, the laser energy will be converted into other forms of energy, such as thermal energy, chemical energy.
Absorption: the absorption of materials on the laser is the key factor in the design, in general, the higher the absorption rate, the higher the processing efficiency, the better the effect.

For CO2 lasers, copper is a highly reflective material, and almost all of the laser is reflected without being absorbed; the reflected light returns to the laser, causing harm. Therefore, most of the cutting metal material is selected as a fiber laser rather than a carbon dioxide laser.

Advantages of Hole Checker

With the high cost of raw materials and labor, the profit space of the enterprise is getting smaller. It has become an important task for enterprises to develop and improve the product quality, reducing industry scrapping. The holes in the printed circuit board (PCB) contain the guide holes, part holes, slot holes, various Heterotypic types of holes, etc. As the accuracy of PCB is higher and higher, the requirements for quality of the hole is higher at the mean time. Another aspect, due to the trend of miniaturization, various hole aperture is becoming more and more small, lead to artificial check error raised. The artificial cost is very high nowadays, demand for hole test machine becomes stronger. The hole checker’s advantages, it can save plenty of space and labor, improving its efficiency. The test items include small holes, slot lengths, slot angles, round hole debris, slotted debris, irregular slot shapes, plate type inspection, etc.
