With over 40 years of experience, CMR Manufacturing
Inc. is the premier Leadframe and Photochemical
Machining Manufacturer in the South West, which is
why they were chosen by a large defense contractor
to assist in the manufacture of parts that were
sent to Mars on (MER) Path Finder, Opportunity and
CMR's complete in-house Engineering and Manufacturing facility
allows them to provide precise hands-on completion of delicate,
complex projects to hearty, robust products that would be extremely
difficult to produce using standard fabrication methods. One of our
many specialties include Leadframe and
Power QFN manufacturing, conforming to
the JEDEC Standard, with Prototype Frames from concept to delivery
in less than a week.
CMR has the capacity and capability to produce extremely fast turn
around times, in order to help our US-based and global clients meet
their critical timelines, without compromising quality or delivery.
CMR's in-house Engineering department incorporates Micro Cad Design,
Helix Solid Modeling, and AutoCAD 2000 software.
We can assist you with any phase of design and development from
simple advice to generating complete product design from your ideas
Just send your .dwg, .dxf, iges, or .pdf files to
or simply fax your document to (602) 244-1312 and our engineering
staff will be in-touch with you in most cases within less than 24

The advantages of Photochemical Machining (PCM) is that the product will not
generate burrs, coining, or unnecessary internal and external stress on
virtually any ferrous and non-ferrous metal, without chemical or physical
manipulation of the material being manufactured. CMR will produce multiple
precise imaging to insure exact repeatability on metal ranging from .001" to
heavy gauge regardless of the temper.
Photochemical machining provides fast turn, excellent accuracy,
repeatability and precise products.
Photochemical machining charges are substantially lower than that of
conventional die fabrication facilities. The cost of changing or modifying
photo tooling is far less expensive than modifying conventional hard
With Photochemical machining the investment is minimal due to elimination of
die maintenance, repairing damaged tooling or long delivery schedules. CMR's
delivery schedule is normally 3 weeks from Purchase Order to delivery.
Reduced delivery times can be accommodated if needed.
Temper and magnetic properties are not affected by photochemical machining.
Photochemical Machining has been around since WWII and very little has changed
except for advances in regeneration and inspection capabilities. Material is
meticulously cleaned to remove any impurities that may be deposited when
delivered. The metal is covered with photo resist exposed to high intensity
lighting, developed to expose material to be removed and finally etched to
Available Materials - Pure Nickel, Nickel
Alloys, Copper, Beryllium Copper, Brass, Phosphorus Bronze, Stainless Steel,
Monel, Kovar, Alloy Material.
We use ½-etching capabilities in our
manufacturing process to support requirements from the Semiconductor
Industry with our proprietary Mold Lock Features, to identifying parts.
Additional ½-etch applications are used to assist in precise repetitive
non-marring distortion free product being bent or formed.
Establishing exact tolerances in photochemical machining are hard to ascertain
due to the fact the type of material used, size of the product, and yield
requirements will affect the tolerance passable. The normal tolerance level is
+/- 10% of material thickness. However for critical requirements CMR has been
very successful in reducing this normality.
Available Finishes include: Tin, Tin-Lead,
Silver, Nickel (Electroless and Electrolytic), Nickel Silver, Gold, Nickel
