Manufacturing

We understand how important time to market is to our customers. To this end, we can have your prototypes ready in as little as 24 hours (depending on the size and scope of the project).

With the flexibility to manage a constantly changing bill of materials, evolving PCB designs, and shifting project schedules you can count on us to build your prototype on time, every time. In addition, we will provide you with design for manufacturability feedback to help you reduce manufacturing cost and time.

We put together all the pieces that make our customers’ products a reality. We assemble and connect the printed circuit boards and backplanes that form the heart of the system. We ensure the mechanicals mesh together, and create the enclosure that protects and houses it all.

Our build-to-order and configure-to-order services assemble a product according to the needs of the individual end-customer. And we integrate the hardware and software – as well as provide functional testing and reliability analysis – to make sure it works for that end-customer right out of the box.

Conformal coatings protect electronic printed circuit boards from moisture and contaminants, preventing short circuits and corrosion of conductors and solder joints. They also minimize dendritic growth and the electromigration of metal between conductors. In addition, the use of conformal coatings protects circuits and components from abrasion and solvents. Stress relief is also provided, as well as protection of the insulation resistance of the circuit board.

Conformal Coatings Options

For conformal coatings, the most competitive options are materials based on: acrylics, epoxies, urethanes, parxylenes or silicones.

• Acrylic

  Acrylic coatings are typically solvent based and are easily repaired. Traditionally they were low cost but have become less competitive with rising regulation requirements and safety concerns with solvent usage. They were tough, hard, and transparent – but lacked stress relieving capability. Pot life was good since additional solvent could be added to keep the bath viscosity low and they exhibited low moisture absorption and had short drying times when volatile solvents were used.

• Epoxy

  Epoxy coatings are very hard, usually opaque and are good at resisting the effects of moisture. They possess excellent chemical and abrasion resistance, but can cause stress on components during thermal extremes. Cure chemistries can sometimes require extra precaution for safe handling. Fluctuating temperatures can cause considerable drift in viscosities and difficulties in controlling cure times and coating thicknesses.

• Urethane

  Urethane coatings are tough, hard and exhibit excellent resistance to solvents. Along with excellent abrasion resistance and low moisture permeability, they offer good low temperature flexibility.

  Their use is often prevented by their limited high-temperature capability and lack of repairability.

• Paraxylylene

  Paraxylylene coatings are very uniform and yield excellent pin coverage. Their limitations include high cost, sensitivity to contaminants and the need for vacuum application technique.

• Silicone

  Silicone coatings range from elastoplastic (tough, abrasion-resistant) to soft, elastomeric (stress-relieving) materials.
  They possess the following characteristics:

  • Heat cure or RTV cure
  • Usefulness over a very wide temperature range
  • Good moisture and humidity resistance
  • Processing versatility
  • Easy repairability
  • Low toxicity
