Conformal Coating Process Decision Worksheet

A common objection we receive from potential customers is that they perform conformal coating in-house as opposed to out-sourcing the coating to a vendor.  Many factors are often overlooked when it comes to conformal coating, so let's go through a process decision worksheet that takes into account many variables before a final decision is reached.  

Is there is an over-riding factor such as the sensitive nature of the boards or production timing issues that make it impossible to outsource coating?  This is rare, but for some very high production volumes or Department of Defense projects, it is just a factor beyond anyone’s control.

What is the complexity of the conformal coating?  Examine the masking, inspection, and coating requirements for their difficulty and complexity.  Decide if they are within your current staff’s means or if any additional training will be required to meet your customer's needs.

Next, consider all of the costs involved including, but not limited to:  Staff payroll, training, floor space, equipment costs (including maintenance), materials costs, and hazardous materials training and disposal.  View a more detailed list on the worksheet.

Total these costs and divide by the number of boards to be coated to get your coating cost per board.  Compare your in house cost with a quote from an outside coating service provider.  Even if the price to perform the coating in house is lower, determine if there will be on-going requirements to payback initial setup and on-going maintenance costs.

We have compiled these questions into an easy to use worksheet so that you can work through the problems presented with your team to determine the best fit for you.  Click the link below to download the conformal coating process decision sheet:
