1. Life: because as laser engraving machines and consumables, laser tube so, life became the most important user purchase policy. PCB engraving machine to understand its composition differences due to his primary processing technology, planning technology and the primary factor. General domestic laser tube working days in 1500 hours (60W).
2. The laser energy: not the same function of the laser tube, the maximum light intensity difference.
3. Spot quality: PCB engraving machine to understand the function of mode choice by laser tube. Beam quality, composed of many links of production technology choice. Spot directly affects the quality of the user application function.
4. Stability: the stability difference of function of products, easy to leakage, non external burst doubt.
The difference of laser tube with foreign CO2 laser: glass laser (laser tube) domestic and imported laser processing to the completion and use of the same basic. In his appearance, layout, function, there is a big difference. PCB engraving machine was found in the quotation of prices also vary greatly, the same power, imported laser is probably several times of domestic laser. (the same life also vary greatly. Import CO2 laser refillable use, domestic glass laser tube in general as a disposable use) therefore, domestic glass lasers, because of low, economy practical quotation has been recognized domestic and foreign customers.
