Central Coating is now offering the latest generation in Form-in-Place (FIP) Gasket Application using UV curing dispensing technology. Conformal Coating provides protection against fungus, moisture, corrosion, thermal and mechanical shock to PCBS.
Polyurethane coatings are amongst one of the most popular choices for conformal coating applications, they are available as single component, two component, UV curable, and water borne systems.
Diamond MT is a class 3 operating, fully functional coating operation with over 25 years of field experience. Conformal coating inspection is a critical factor in determining successful coating application and long term reliability of PCBs.
We are committed to serving the industry with rapid turn times for parylene, (normally 10 business days) with expedited service in as little as 2-5 business days depending upon the complexity and quantity. Diamond MT's quality manual ensures every employee is focused on continuous improvement and service excellence. In the second part of a two-part series of articles, AZoM talks to Masterbond about the properties and benefits of conformal coatings.
However, irrespective of the application method used, it is vital to begin with a clean and contaminant-free surface to enhance adhesion. The thickness, design, and operating parameters of the eventual application have to be determined keeping the processing in mind.
In order to select a suitable conformal coating, the main application need has to be taken into account. The next aspect to be considered is the specific environment to which the assembly will be exposed. Additional factors involved in the selection of a conformal coating include application time, reworkability, cure time, and capital and labor costs.
In order to prevent electrical breakdown of the coating, high dielectric strength is very important.
Conformal coatings considerably improve the longevity and reliability of high-performance electronic printed circuit boards.
They are capable of protecting electronics from environmental conditions that can hinder circuit performance and promote premature failure.
A range of conformal coating compounds and processing methods provide innumerable options to manufacturers who wish to extend the life of their products across various industries.

Conformal Coatings - Environmentally Friendly Conformal Coatings for Electronic Circuitry by Master Bond Inc.
Essential for protecting electronic circuitry and significantly extending the service life of printed circuit boards, conformal coatings are an integral component of the entire sub-assembly. Use of any Novagard Solutions™ trademark is not permitted without prior written permission. This process and material is used for sealing Plastic, Glass, Metal and Plated surfaces and enclosures. Our in-house ability to manufacture custom masking plugs and boots ensures process reliability and quality while reducing cost. As a group, all provide excellent humidity and chemical resistance plus outstanding dielectric properties for extended periods; which make them one of the more popular coatings when it comes to protection of the critical operation of your printed circuit boards (PCBs). The selection of conformal coating material is a crucial factor that needs to be considered carefully and in relation to the application method. These standards list indications of good and bad coverage and describe various failure mechanisms such as de-wetting and orange peel. Using the IPC standards allows the coating operator to monitor the coating application performance. For liquid coatings, our normal turn time is five business days; again with expedite service in as little as 2-3 business day turns.

Our ESD safe facilities stretch over 12,000 square feet dedicated to your conformal coating requirements.
Depending on the nuances in the production settings, the most suitable techniques are used.
Conformal coatings can be applied by dipping, spraying, flow coating or any other conventional processing technique. When thermal stability or stress relief is important, a silicone coating provides a suitable solution.
Severity and duration of contact, heat, humidity, shock, stress, vibration, the types of contaminants, and degree of mechanical stress are other important factors that dictate the suitable combination of coating properties.
For example, UV curable coatings are usually recommended when processing speed is important, as long as limited temperature and chemical resistance are satisfactory. These compounds exhibit the advanced properties required for a number of different industries, including the aerospace, medical, optical, electrical, electronic and other manufacturing industries. The dispensed gaskets acts as a moisture seal preventing air, dust, liquids, gaseous substances and dirt from penetrating the enclosure. The wrong selection can not only affect the long term reliability of the circuit board but can cause massive difficulties with both processing and costs.
This can be done manually by the operator in an inspection booth by examining the PCB under white and UVA light or it can be done automatically by a conformal coating inspection system. We are continually researching and updating our equipment to make sure we are providing the best ESD protection available. When there is a thermal variance between the coating and the components, flexible coatings that can bend without delaminating or cracking are extremely important.
It offers a complete solution for cost-efficient and rapid realization of powerful stand-alone sensors so that they can function in a process controlled setting. The ability to UV cure in seconds allows for faster and greater outputs and lower processing costs. Our Standard lead-time is 5-7 days and we also offer quick turnaround in as little as a day.
