Why Pro-Active Engineering Stands Out

We are a full-service Electronics Manufacturing Service (EMS) provider. We are a small business that gets things done. Our roots are in electrical engineering and we provide our customers with the flexibility that large companies lose track of. Our ingenuity and grit have led to the mastery of complex boards designs and assembly requirements.
