Photo Etching Process Typical Manufacturing Steps

Step #1

CAD Artwork

Via customer's blueprint, or electronic transfer file, VACCO's photographic artwork is laser plotted to exacting specifications.

 Step #2

Applying Photo-Resist

VACCO employs either dryfilm or liquid resist for the transfer of the photographic image to the panel of material.

 Step #3

Imaging Panels

Microprocessor controlled UV exposure ensures exact image transfer from the precision photographic artwork to the panel of material.

Step # 4

Metal Etching

As one of the largest commercial etching facilities in the U.S., VACCO's multiple etching lines offer both high volume capacity and prototype flexibility. Etch operators employ SPC on all products.

 Step #5

Photo-Resist Removal

Proprietary formulations are often used on critical applications. Pictured is a multi-laminate copper panel being sprayed with a customized resist removal solution.

Step #6

Inspection

Visual inspection, assembly, testing and other operations are performed in a dust-controlled environment.

Step #7

Water and Air Treatment

VACCO remains proactive on environmental responsibility. An automated wastewater facility is supported by our on-site staffed chemical analysis laboratory.
