INDUSTRIAL

Calpak USA applies conformal coatings selected to match the specific environmental threats each industrial assembly will face in the field. Available chemistries include acrylic coatings for general-purpose moisture and dust protection, urethane coatings for superior chemical and solvent resistance in process industry environments, silicone coatings for assemblies operating across wide temperature extremes from minus 65 to plus 200 degrees Celsius, and Parylene C or HT deposited via chemical vapor for uniform pinhole-free coverage on complex board geometries. At our Hawthorne, California facility, Calpak USA technicians mask connectors, test points, adjustment potentiometers, and thermal management interfaces before applying coatings per IPC-CC-830 requirements. Coating thickness is verified using eddy current or optical measurement tools, and adhesion testing confirms proper bond to the solder mask surface. For industrial OEMs whose products operate in chemical plants, food processing facilities, or outdoor installations, Calpak USA recommends the coating system that addresses the specific moisture, condensation, and contamination profile of the deployment environment.

Calpak USA's component engineering team supports industrial OEMs by sourcing semiconductors, passive components, and connectors rated for extended temperature ranges beyond standard commercial specifications. Industrial applications frequently require components rated for minus 40 to plus 85 degrees Celsius at minimum, with some process control and outdoor installations demanding full military temperature range of minus 55 to plus 125 degrees Celsius. At our Hawthorne, California facility, Calpak USA verifies temperature ratings against manufacturer datasheets during the BOM review phase and flags any commercial-grade parts that may not meet the customer's specified operating environment. Our approved vendor list includes distributors authorized to supply industrial and automotive-grade components with full lot traceability and certificates of conformance. When drop-in extended temperature alternatives are not available, Calpak USA's engineers work with the customer's design team to identify functional equivalents from qualified manufacturers, documenting the substitution rationale and obtaining customer approval before procurement.

Calpak USA provides potting and encapsulation services for industrial assemblies that require protection beyond what conformal coating alone can deliver. Two-part epoxy, polyurethane, and silicone potting compounds are dispensed into customer-supplied or Calpak USA-fabricated enclosures to fully encapsulate PCB assemblies, protecting them from sustained moisture immersion, mechanical vibration, thermal cycling, and chemical exposure encountered in industrial field installations. At our Hawthorne, California facility, Calpak USA controls potting compound mix ratios, vacuum degassing procedures, and cure temperature profiles to prevent void formation and ensure full coverage around components and solder joints. For assemblies with heat-generating components, thermally conductive potting compounds transfer heat to the enclosure walls while maintaining electrical isolation. Calpak USA's process engineers evaluate each design for potting compatibility, identifying components that require pre-protection or heat sinking before encapsulation. This service is particularly valuable for industrial sensor modules, outdoor power supplies, and motor drive electronics deployed in environments where IP67 or IP68 ingress protection ratings are required.

Industrial products commonly remain in production for ten to twenty years, far exceeding the lifecycle of many electronic components. Calpak USA's component engineering team in Hawthorne, California actively monitors end-of-life and product change notifications from semiconductor manufacturers and distributors through automated alerts integrated with our ERP system. When a component reaches last-time-buy status, Calpak USA notifies the customer with lead time and quantity information so they can authorize a lifetime buy or initiate a redesign. Our engineers maintain a pre-qualified alternate parts database for common component categories, enabling faster cross-reference when substitutions become necessary. For customers who authorize lifetime buys, Calpak USA provides bonded inventory storage with proper humidity-controlled conditions and first-in-first-out rotation management. This proactive approach to obsolescence management prevents the production line stoppages and emergency redesign costs that industrial OEMs face when critical components unexpectedly become unavailable, protecting both manufacturing continuity and product revenue streams over the full program lifecycle.
