Questions to ask when considering a Conformal Coating Dipping Application

When selecting a conformal coating process it is important to ask the right questions.

With dip coating, the information required includes questions such as:

  1. What is the size of the Printed Circuit Board (PCB) you wish to coat?
  2. What is the typical volume of the PCBs you want to coat per day, week, month etc?
  3. Is there any masking required on the PCBs?
  4. Do you know how you would like to hold the PCBs or do you need help with fixture design etc?
  5. Is the PCB to be dipped vertically, horizontally or at another angle?
  6. What is the material you wish to use for coating the PCB?
  7. Is the material compatible with a dip coating process?
  8. Do you require a batch process (operator loads and unloads at same point) or an inline process (load one end and take off at another station)?
  9. Do you require any curing mechanism within the machine (heat cure, UV light)?
  10. Do you require any automated control processes such as viscosity material maintenance and automatic material top up?

Asking these questions ensures that a dip coating machine supplier can provide a detailed quotation on the exact machine you need for your project.

About Dr Lee Hitchens

Dr Hitchens has been working in the electronics industry and the area of conformal coatings for over 25 years in various areas including sales and technical support. He has also been training people for almost the same amount of time in all areas of conformal coating whether that is materials & equipment selection, process development or troubleshooting to help them solve their particular problem. Recently, he decided that the industry needed a specific place where all of the useful knowledge on conformal coatings could be collated for users to find easily and use in their own production process. So, Nexus was born and he began the Nexus eBook project.
