Nexus Series of Webinars: Conformal Coating Rework, Repair and In Process Application

Nexus are to hold a series of webinars on conformal coating topics in the Autumn of 2012.The series of four online conformal coating webinars will cover the following topics and each last 90 min. The last of the online training webinars will be:

Rework, Repair & In Process Application
Monday 4th February Rework of coating boards is a skilled job to obtain the optimum product reliability. Different materials or thicker coating may require different techniques to maintain the same reliability provided by the original coating system. It’s not always possible to use the same coating system in a rework situation so what are the alternatives?

Topics will include:

Material identification
Conformal Coating removal techniques
Cleaning & preparation
What coatings are compatible?
Re-coating assemblies after rework
Inspection of coatings after rework

Ask The Expert: Dr Lee Hitchens, Nexus on Key Conformal Coating Material Challenges

“Out of all the Key Material Challenges I see on a regular basis, one of the most prolific is difficulties in adhesion to solder resist or to no clean residues and contaminants.“
 “It can be as basic as the coating just will not stick to the PCB or it runs away from areas on the PCB. At other times, it’s interpreting just how well the coating is stuck and determining if it’s good enough for the customer? Normally, this cannot be answered instantly and leads to some serious thinking!”

Ask The Expert: Karl Hardcastle, SCH Services Ltd, Subcontract Conformal Coating Service on Key Conformal Coating Material Challenges

“One of the biggest issues we face is availability of the materials. As a subcontract coating house we generally have to use the coating selected by the customer. This can have dramatic issues occasionally when lead times on products can stretch into weeks or months and the customer wants the product now!”
“Conformal coating is one of the last processes on the PCB. Coating houses are normally making up the time lost in other areas. If you can plan the production to coincide with the material supply chain it’s a great help!”

Ask The Expert: Gordon Watson, SMS Automation, Conformal Coating Equipment on Key Conformal Coating Material Challenges

“Our greatest Challenge is establishing good communication at an early stage with the key decision makers to determine the critical factors such as material specification, performance and requirements. Customers should also think of future needs when discussing conformal coating application systems rather than limit their choices to what is available on a standard machine.”

“Our skill is in combining machine building and automation skills with knowledge of the process of conformal coating and so it is important that we obtain a thorough understanding of our customers’ requirements and quickly formalise them into a  plan as quickly as possible.”
