Capital Electro-Circuits continues its investment ... to improve our ability to meet our customer's requirements.

We would like to bring our valued customers up to date on some of our improvements we have made in the past several months.

Microcraft / Lavenir Mp220 Fixtureless, Four Head Flying Probe Electrical Test Machine

High speed electrical testing without a fixture. Test voltages up to 250 volts, double sided surface mount pads, and a minimum SMD pitch of 0.010 in.

Using this latest advancement in bare board electrical testing technology, we can offer you a fast and economical option for netlist testing your complex prototype boards.

With this upgrade we can download a PCB's netlist and test the board against the netlist as a opposed to a golden board. Netlist testing conveys a higher degree of confidence compared to golden board testing while providing an economical method of testing high quanities of boards.

Using the PCB netlist, Gerber files, and test results, this program highlights failed test points, and the location of probable opens/shorts on a computer screen for quick and easy debugging and repair.

One of the most powerful CAM stations available in the industry. Capabilities include netlist extraction (including blind and buried vias), netlist comparison, wide selection of input/output formats, advanced Design Rule Checking, and more.

Many new features have been added to this latest version providing more accurate and efficient CAM operation.

Used by our shipping department, this system seals printed circuit boards in a vacuum environment surrounded by bubble wrap for the ultimate protection during shipping and storage. Since the PCB is vacuum packaged, the solderability protection is enhanced and the shelf life is prolonged considerably.

Vertical Hot Air Solder Leveling (HASL), this machine is specifically designed to yield a uniform solder coating on PCBs with SMD on one or both sides.

Dedicated to the final cleaning, removes any chemical residue from PCBs prior to final inspection and packaging.

Used prior to Liquid Photoimageable, (LPI) solder mask application, this newly developed high speed dryer prevents copper oxidation by removing moisture.

We offer a wide selection of materials that can be stocked and processed at our facility, icluding: Taconic, Rogers RO3000, RO4000, Teflon, Ceramic and more. We also have the capability to perform specialty processes such as; edge plating (complete and selective), immersion gold, immersion tin, mixed dielectric multilayer, plasma cleaning, controlled dieclectric thickness, and more.

Including: PCB Design/Layout, PCB Fabrication, Assembly, Wire Harness, Box Assembly, and Parts Procurements.

This additional space was added to accommodate our expanded testing capabilities, pre-engineering, Inspection, Business Offices / Conference Room facilities, and to provide additional space for manufacturing as needed.

We recognize that to meet our customer's diversified and ever-changing requirements we have to reinvest a portion of our sales in better capabilities and improved facilities. We look forward to developing a stronger partnership with our customers by continuing to develop the capabilities to meet or exceed their needs.

Capital Electro-Circuits will be exhibiting their line of Printed Circuit Boards at the SMTA Learning Institute being held at the Turf Valley Convention Center, Ellicott City, Maryland on Tuesday April 29 1997. The SMTA learning institute provides a look at the latest developments in Ball Grid Array, Chip Scale Packaging and various new technologies for high density Printed Circuit Boards for use in PCMCIA, MCM-L and other new electronic products. We look forward to seeing you.

Capital Electro-Circuits announced the new capability of Top Of Circuit Depth Control (TOCDC) and scoring. The TOCDC allows precise depth control (+/- 0.001 inch) across the panel. The key advantage of this system is that the depth control is maintained relative to the surface of the board unlike convention fixed z-axis depth control which does not compensate for variation in surface flatness. What it means to our customer is that now we can provide precise depth for blind vias, counter bore/sync and beveling. Further, now we have in-house capability for scoring. Many customers prefer scoring over individual routing for efficient assembly, where the entire panel is assembled at the same time.

Capital Electro-Circuits announced the capability to offer the option of selective carbon ink printing on the circuit board for keypads and other contacts. The carbon ink provides outstanding reliability and wear resistance for PCB keypads and it offers a cost effective option for gold plated edge contacts as well.

Gaithersburg, MD - Capital Electro-Circuits, Inc. announced an installation of a Hot Air Solder Leveler (HASL) specifically designed for SMT boards from Avalon Technology. "With growing demand for fine pitch surface mount boards, the thin uniform solder coating on SMT pads is extremely important for high yield during the assembly operation. With this uniquely designed machine we are now consistently getting the desired uniform coating thickness" said Gary Gindlesperger, "We are tailoring our company to meet the special needs of the surface mount boards industry. We also recently installed a new copper plating line, which is also specifically designed for uniform plating across the panels. The combination, even copper plating and even solder coating, means superior SMT board finish," further stated Gary Gindlesperger.

CEC has been in business since 1985 and has customer base of over 600 customers nationally and internationally.
