Contact Information
VPT, Inc., a Heico company, is dedicated to the highest
level of quality. With expert, experienced personnel,
state‐of‐the‐art technology, and strict quality procedures,
VPT produces reliable power supply products for the
demanding environments of avionics, military, and space
environments.
VPT products are designed and produced at MIL‐PRF‐
38534 certified, MIL‐STD‐883 lab suitable, and ISO9001
registered sites. VPT's R&D headquarters are in
Blacksburg, VA, manufacturing is at Delta Electronics, Inc.
in Taoyuan, Taiwain, and sales and marketing facilities are
in Bothell, WA.
VPT employs a comprehensive Quality Assurance System to ensure that all products are designed, developed,
manufactured, tested, stored, and delivered in compliance with all government and customer specified and
contractual requirements. The System includes detailed policies, objectives, plans, and methods to ensure that
requirements are effectively implemented and to provide defect‐free products through concurrent engineering and
process controls.
The VPT Quality Assurance System utilizes a proactive approach to ensure the design quality of products prior to
manufacturing. VPT’s System manages design and process quality rather than product defects. This is achieved
through a complete set of quality procedures, which include process capability, quality management methodology,
supplier quality control, component and raw material standardization and minimization, process control and
capability studies, and design assurance. The System provides for the early detection of actual and potential
deficiencies, system incompatibilities, marginal quality, trends, and any other conditions which could result in reduced
performance. Finally, VPT’s System enables VPT to provide effective and timely action to correct any such conditions.
VPT’s Quality Assurance Manual (QA1‐001) and System includes more than 300 specific quality and process
procedures. These procedures detail VPT’s configuration and documentation/software/record control, responsibilities
and authorities, contract review, self auditing, calibration, cleanroom and facility control, ESD control, testing,
processes, manufacturing, qualification, training, and all other aspects of each requirement and function performed.
When pertaining to quality, every requirement and procedure is documented and every action is recorded. This
document highlights a few key aspects of VPT’s Quality Assurance System, certifications, and policies. VPT welcomes
customer inquiries into any areas not specifically covered in this document. Please contact your sales representative
or the VPT Sales Department for more information.
