Contract Manufacturing, Electronic Assembly,
PCB Repair | Rework, & Semiconductor Fabrication
Manufacturers & Services

Long gone are the days when electronics products were assembled in the same physical location where they were designed - at least for medium to high density circuit boards. Virtually all modern consumer electronics products are assembled, tested, and packaged by companies whose primary business is volume manufacturing. They are referred to as Contract Manufacturers (CM). Many CMs have expanded their capabilities to include assistance in design optimization. Some can even help tweak integrated circuit masks for "cookie cutter" items like ESD and reverse polarity protection. Another type of CM is one who makes specialty products like filters or amplifiers and offers to design and manufacture customs versions for the customer (you). Although rare, some of those specialty companies can arrange to have your entire design manufactured.

Please consider contacting RF Cafe advertisers first.

My policy is to only list companies that actually manufacture product or offer services related to the page title subject. Product distributors and sales representatives are not listed (they have their own page). This helps guarantee that each listing offers a unique product or service. NOTICE: I am no longer adding hyperlinks due to so many companies asking to be removed because of some issue with Google Statistics. Your best bet is to use a search engine to find company websites directly. If you are interested in advertising, please visit my Advertising information page.

Fusing Imagination with RealitySM

Founded on the near-limitless potential of Electron Beam Welding, EBTEC has more than 50 years of experience executing precision high energy beam processes as well as traditional fabrication solutions for our clients' specific challenges.

Electron Beam Welding can be used to join metals and alloys to themselves or each other with high repeatability and virtually no distortion. We have the largest EB welding chamber on the East Coast.

Laser Cutting can produce exact, minimal-kerf cuts with extremely high repeatability. We can perform 5-and 6-axis and flat sheet cutting.

Laser Drilling can deliver angled and difficult access holes on alloys and composites that cannot be drilled by conventional methods.

Laser Welding can join multiple kinds of metals and alloys to themselves or each other without fillers or fluxes. Laser welding joins ferrous metals, stainless steel, precious metals, and alloys with no secondary finishing required.

Waterjet Cutting is a nonthermal process employing high-pressure water capable of cutting metals, ceramics, super alloys, granite, and more.
