As circuits become smaller and their presence more ubiquitous, PCBs are being assaulted by every conceivable environmental stress. From dropping a cell phone to launching sensitive equipment into the depths of the oceans or the radiation of space, developing a PCB can be as much about manufacturing as about anticipating the life it will lead. At eTech, we know how to safeguard your boards from the rigors of the real world, extending their useful life and ensuring they perform as you intend.
Underfilling can dramatically extend the useful life of a device, protecting solder joints from extreme temperature changes, vibration, chemical exposure and other environmental stresses, while ensuring that devices work efficiently and experience the longest possible useful life.
The most perfectly performed rework and assembly can be quickly ruined by environmental exposure. eTech technicians understand how to choose the right coating chemistry for your device, and make sure the coating is applied precisely.
Environmental stresses can make some coatings ineffective. In the same way that we choose an underfill based on variations in temperature, moisture levels, vibration resistance, and other expected considerations, our technicians understand how to balance moisture, temperature variation, chemical exposure and other factors to choose the right conformal coating for your boards.
Coatings are applied using precise methods, creating a breach-free coat of exactly the right thickness. Coatings can then be cured using UV light or one of our five ovens.
