With electronic gadgets increasingly playing a part in daily life, the various applications for electronic systems or gadgets continue to develop at a rapid pace. Standard semiconductor manufacturing technology is ever-increasing, with systems expected to perform more operations, more quickly and reliably, while becoming smaller as well as lighter with every design iteration.
As circuit board assemblies become ever more densely populated, and housing or casing designs become more permeable to save the weight of the boards, the use of 3 axis selective coating machine for conformal coatings is becoming essential to protect the circuit board assembly from its operating environment. It not only ensures acceptable reliability for the application but also improves the hostile operating environments. Thus, increase productivity, reduce cost, and mitigate risk.
Why Use Selective Coating for PCB Assembly?
Conventionally, selective or conformal coatings are very, very thin polymeric materials that are intended to protect the assemblies from different types of harsh conditions experienced in their hostile operating environment, including moisture, condensation, salt-spray, corrosive gases, and conductive particles, to name a few. If you are in this industry for years, then you must know that coatings can also provide further dielectric insulation. It allows components to be placed in closer proximity than will be possible in the air, and to reduce risks against the growth of tin whiskers.
To fully protect against the corrosion as well as provide an effective barrier to reduce the risks against tin whiskers that can potentially cause connection failure in electronic circuit boards by shorting the circuit, then the coating material should be covered all metal surfaces. These metal surfaces need appropriate thickness to give these barrier properties, and a 3 axis selective coating machine works better for this job.
Advantages of using 3-axis Selective Coating System
The 3 axis selective coating machine SC-345 with high precision coating value is no doubt a practical as well as affordable selective coating system. It adopts a step motor and helps synchronous the belt driving system that can ensure +-0.06mm repeatable accuracy. The maximum coating areas can reach 400mm*450mm.
The XYZ axis has with step motor and its high standard driving system. It has a high precision coating value. It is 400mm*450mm maximum of Printed Circuit Board width capable. It is built with industrial PC, and Windows XP operating system, and the interface is in English.
