Precision epoxy dispensing helps electrical manufacturer improve quality and yield

Parkinson Harness Technology was looking to satisfy a customer’s need for a way to pot a small electrical resistor into the bottom of a diesel filter bowl without compromising the connectivity of the copper pins. The process needed to be accurate, repeatable and reliable whilst minimising wastage of parts and material. Intertronics’ product specialist, Simon Gibbs, worked alongside senior development engineer Clayton Smith to find an efficient way to pot the resistor with higher accuracy and precision than the existing method. He conducted a series of trials and demonstrations in order to establish a more suitable method of dispensing. Describing the original process Clayton said: “Our existing process was just not working for us or the customer; we had a high failure rate and a lot of rejected material, so something needed to change.” He continued: “We looked at several different solutions from a handful of different companies, but the offering from Intertronics stood above the crowd. This, coupled with the positive approach from Simon Gibbs and everyone else on the Intertronics team, convinced us that we had found the right solution.” Once satisfied, Clayton proposed this new process to the customer, who was happy to go ahead with the new method, resulting in better quality products at a reduced cost due to the reduced material waste and reject rates.
