CCL, also known as Copper Clad Laminate, is the foundation material of PCB. Selectively processing like etching, drilling, copper plating on the CCL leads to PCB of different types and different functions. CCL plays an important role in the interconnection, insulation and supporting of the PCB. It is also closely related to the signal transmission speed, manufacturing level and manufacturing cost of the PCB. Therefore, the performance, quality, manufacturing cost and long-term reliability of PCB are decided by CCL to a certain degree.
As electronics have more and more varieties, PCB is experiencing an increasing demand. Therefore, the supply of double-sided CCL is also increasing. Double-sided CCL requires certain processing technique to do the slitting and this makes UV laser cutting machine an ideal tool.
Why UV laser cutting machine is an ideal tool in double-sided CCL slitting? Well, that is because double-sided CCL is very thin and light-weight. Traditional slitting techniques would lead to burning or deformation of the CCL. But UV laser cutting machine won't have these drawbacks, since the UV laser source is a kind of “cold light source”, which means it has very small heat affecting zone and won't damage the CCL surface. The slitting processing using UV laser cutting machine is pretty efficient and precise.
For the time being, double-sided CCL is widely used in aerospace device, navigating device, consumer electronics, etc. This is a good trend for the supply of double-sided CCL and choosing a machine that can provide easy CCL slitting is quite important and necessary.
In addition, using UV laser cutting machine for CCL slitting has low energy consumption, which can reduce the operating cost for the manufacturers. As the price of the raw materials, factory rent and human labor cost increase, manufacturers using traditional processing methods are bound to have lower and lower profit. To have bigger profit in the fierce competition, manufacturers have to consider replacing with new processing technique and automation technique. And UV laser cutting machine would be a very good choice.
To keep the UV laser cutting machine running normally, a mini water chiller is a MUST. That is because precise temperature control would guarantee the stable output of the UV laser source which decides the cutting performance of the UV laser cutting machine. S&A CWUL-05 mini water chiller is often seen as a standard accessory for UV laser cutting machine because it's easy to use and install and it can deliver high precision temperature control of ±0.2℃. Plus, it is not consuming much space. For more information about CWUL-05 mini water chiller, click https://www.teyuchiller.com/compact-recirculating-chiller-cwul-05-for-uv-laser_ul1
