Looking into possibly receiving samples of polyester masking dots for conformal coating. Our usage of polymide dots have really increased in the past months and we're always looking for a reduction in costs. The only information I've found is that polyester tape has the same static properties of polymide at room temperature but can change with increased and decreased temperature.
Anyone familiar using polyester tape on assemblies? Any positive or negative experiences?
Polymide rolls of dots are at around $25 while polyster is at $14.
