Reliable Thermoformed Solutions by Fralock

Fralock utilizes a unique pioneered polyimide lamination process, Adhesiveless Lamination Technology (ALT) that eliminates the use of adhesives. Adhesiveless laminates provide high temperature resistance, dimensional stability, low outgassing, durability, and solvent resistance. Traditional polyimide laminates are notoriously unreliable at temperatures that exceed the Glass Transition (Tg) of the adhesives used in their construction.

Polyimide is closely matched to the CTE of copper, and can also be used to bond many other metals with bond strengths typically > 10 pli. If your application requires high temperature resistance, dimensional stability, low outgassing, durability, and solvent resistance, adhesiveless laminate technology is the solution.

We provide high-quality custom flex and rigid-flex circuit fabrication and electronic assembly solutions.

Conformal Coating
We provide the following assembly processes for your Flex and Rigid-Flex requirements:
We offer protective coatings that are required in electronic circuit assemblies. Conformal Coating applied to electronic circuit assemblies protects against moisture, dust, chemicals, and temperature extremes.

  • Underfilling Encapsulation – protects in flip-chip packaging, reduces stress on solder bumps of chips, and protects against moisture, ionic contaminants, thermal vibration and shock.
  • Potting Materials – Protects the electronic assembly against vibration/shock, corrosion, and chemicals. Also provides electrical insulation, enhanced mechanical strength and heat dissipation.
Our plastic injection molding services include prototype, low and mid-volume production.

Industrial Ceramic Processing
Laser Cutting Machine
Laser cutting service offers operators a highly accurate method of cutting complex shapes from a wide variety of materials. Our laser cutting services focus on extremely fine points and have enough energy to cut through thick materials with ease. Computer aided design (CAD) and computer numerical control (CNC) technology allows complex designs to be made by automated CO2 laser cutting machines quickly and with great accuracy. Laser cutting machines are integrated into a larger CAD/CAM (computer-aided-design, computer-aided-manufacturing) system that takes a design file and implements it on a work piece. These machines represent a stepping-stone in the continuing trend away from hands-on manufacturing, putting human workers in a more removed, creative design role.
