Precise Assembly Solutions, Inc., formerly Z-Optics, is a woman owned corporation. We have been assisting manufacturers with their outsourcing needs since 1994. The services we offer cover all stages of the assembly process.  From our facilities in Merced, California we provide Original Equipment Manufacturers (OEM) with unmatched quality and customer service.

We are committed to developing long term partnerships with manufacturers and suppliers. Our commitment is backed by competitive pricing and a wide range of services. The PAS team takes great pride in the services that we provide, and the companies we serve.

In today's day and age where automation is the standard, PAS, Inc. is proud to have an experienced team that excels in the art of hand assembly.

Precise Assembly Solutions, Inc. is currently seeking manufacturers looking to outsource the assembly of their products, or a fraction of, for reasonable, cost saving rates. We have a fully trained team of individuals ready to get started on your project.

The assembly of all products is done according to written procedures provided by manufacturers. This ensures that all completed work is done exactly to your specifications.

Another service that PAS, Inc. provides is the debugging of written procedures. In some instances, written procedures do not translate well into production. Time management is often a factor. The PAS team can document the areas that hinder the flow of production so that the manufacturers can maintain the most streamlined written procedures for their product. 

We are extremely thankful for the opportunities that have paved our way, and for those that will continue to drive our business.  We believe that our passion for what we do will translate into success for the companies we do business with, as well as for ourselves. We provide a highly efficient service that ensures manufacturers receive the best possible benefits from their outsourcing efforts.
