Located in a 10,000 square foot facility, SEAS offers a wide variety of assembly technologies as well as warehousing and shipping of products.


J-STD-xxx indicates a standard developed through the coordinated efforts of multiple standard developing organizations. After most Department of Defense soldering standards were cancelled in June 1995, most Class 3 users have chosen to use the industry consensus standard J-STD-001.

IPC Classes 1, 2, 3

Electronic assemblies can be divided into three main categories depending mainly on their end use and the level of record-keeping that is required.
  1. General Electronic Products - Includes limited life products suitable for applications where the requirement is function of the completed product.
  2. Dedicated Service Electronic Products - Includes products where continued performance and extended life is required, and for which uninterrupted service is desired but not critical.
  3. High Reliability Electronic Products - Includes products where continued high performance or performance-on-demand is critical, product downtime cannot be tolerated, and the product must function when required.

Depot Repair

A customer-accessed software system and a secure inventory area combine to enable SEAS to receive assemblies for repair and track them through the process. Repaired units can be shipped to end customers as needed.

BGA and BGA Rework

Popular surface mount chip package that uses a grid of solder balls as its connectors, noted for its compact size, high lead count and low inductance. Specialized equipment is required for inspection and rework of these chip packages.

SMT and SMT Rework

The technique of mounting electronic circuit components and their electrical connections on the surface of a printed board, rather than through holes in the printed board.

PTH and PTH Rework

The technique of mounting electronic circuit components using pins that are inserted into pre-drilled holes on the printed circuit board from one side, and then soldered to pads on the other side.

Electromechanical Assemblies

This type of assembly can include a PCB assembly along with a chassis or rack for mounting, power supply, and wiring harness or cables. SEAS maintains a network of vendors to supply sheet metal or plastic enclosures, power adapters and more while wiring harnesses and cable assemblies can be completed in-house.

Mechanical Assemblies

Usually, this category includes assemblies that do not carry any electrical current. Examples would be worm gear assemblies, setting pems into enclosures, etc.

Mixed technologies

Printed circuit board assemblies that have some components placed using SMT, and others placed using PTH.

Box build

A system of integrating all of the parts of an assembly into a final product, for example, populating a printed circuit board, placing it into an enclosure, and attaching a cable assembly for power and/or communication.


The system of procuring all of the components needed to complete a product.


A system where the customer procures and provides some or all of the components necessary to complete a product.


While the US has not banned lead in electronics, many countries have already enacted legislation to remove lead from printed circuit board assemblies.

Wiring Harnesses and Cable Assemblies

A wire or cable harness is a bundle of wires (or cables) usually with a connector of some type on either end. A harness simply replaces individual wiring. Used in a wide range of electronic and electric products, a harness greatly simplifies the assembly process. SEAS's experience includes the techniques of running, tying, terminating and labeling all types of harness assemblies.

Secure Inventory Area

A limited access area with labeled shelving and bins for receiving, inventorying, and releasing component parts as needed to complete particular customer assemblies. Tracking and recordkeeping are possible for Class 3 assemblies, with paperwork retained for a number of years, usually by mutual agreement with each customer.

SEAS has an established and competent vendor base as well as expertise in the following manufacturing processes and disciplines: injection molding, metal stamping, sheet metal fabrication, machining (plastic and metal), bonding/joining (mechanical, adhesive, and sonic welding), and decorating (pad transfer printing).
