PCB DESIGN SERVICES
A Manufacturing MentalityFor more than 60 years, Epec has continued its tradition of perfection in engineering and manufacturing printed circuit boards for the most discerning customers. Our years of manufacturing experience provide us with a competitive edge when it comes to PCB layout and design. From a simple single sided board to a complex multi-layer, double sided surface mount design, our goal is to provide you a design that meets your requirements and is the most cost effective to manufacture.
We pride ourselves on providing high quality design and layout services, but it is equally important that our customers can manufacturer their parts in the most cost effective manner. Our goal is to reduce the overall cost of our customers product by designing a circuit board that can be easily manufactured by Epec or anyone else in our industry.
REVERSE ENGINEERING AND SCANNING
With the consolidation of the printed circuit board industry over the last few years, many of our customers find themselves needing to order boards but they have no electronic data. Their previous supplier may have gone out of business and the only copies of the artwork or electronic data have been discarded.
At EPEC, we can create electronic data from virtually anything, including, films, drawings (DXF), 1 to 1 paper plots, and even boards themselves.
We have over 10 years of experience in creating electronic data from all types of media using our state of the art scanning equipment and software. We have developed a systematic process to make sure that all of the board features are double checked to ensure that everything has been replicated properly. We understand how important it is to get even the smallest details right when it comes to our customers circuit boards.
Please contact your sales representative for more specific details around our design and manufacturing guidelines.

THERMAL CLAD AND METAL BACKED PCBS
Epec offers Thermal Clad PCBs which is a dielectric metal base with a bonded copper circuit layer. This creates superior heat transfer to help cool components while eliminating problems associated with managing fragile ceramics. Thermal clad is a unique layered system comprised of the follow layers:
Circuit Layer: Printed circuit foil with thickness of 1 oz to 5 oz.
Dielectric Layer: Many different options which offer electrical isolation with minimum thermal resistance. Also used to bond the circuit layer and base material together. Each specific dielectric has its own UL recognition.
Base Layer: Most often Aluminum, but can also be copper. The most commonly used thickness is 0.040 (1.0 mm) although many thicknesses are available.
THERMAL CLAD PCB APPLICATIONS
Power Conversion: Thermal clad offers a variety of thermal performances is compatible with mechanical fasteners and is highly reliable.
LEDs: Using Thermal Clad PCBs assures the lowest possible operating temperatures and maximum brightness, color and life.
Motor Drives: Thermal Clad dielectric choices provide the electrical isolation needed to meet operating parameters and safety agency test requirements.
Solid State Relays: Thermal clad offers a very thermally efficient and mechanically robust substrate.
Automotive: The automotive industry uses Thermal clad boards as they need long term reliability under high operating temperatures coupled with their requirement of effective space utilization.
Improve the durability and performance of your product by using Thermal Clad PCBs. Simple designs and low thermal impedance of the dielectric out performs all other PCB insulators for power and high-operating temperature components.
Thermal Clad PCB Materials: Bergquist Thermagon Arlon Denka
Thermal Clad PCB Specifications: 1 & 2 Layer Dielectrics HASL, ENIG & Pb Free HASL finish Up to 5 oz finished Cu Al & CU base material up
to .250 thick
Thermal Clad PCB Benefits: Lower Operating Temperatures Improved Product Durability Increased Power Density Increased Thermal Efficiency Reduced Number of Interconnects Lower Junction Temperatures Reduced PCB Size Eliminates Older Hardware Minimizes Labor Required for Assembly Wide Variety of Form Factors Minimize Thermal Impedance

HDI HIGH DENSITY INTERCONNECT PCB
HDI boards, one of the fastest growing technologies in PCBs, are now available at Epec. HDI Boardsmay have blind and/or buried vias and often contain microvias of .006 or less in diameter. They have a higher circuitry density than traditional circuit boards using less layer construction.
Since the late 1980's we have seen video cameras using cartridges the size of a novel, shrink to fit in the palm of your hand. Mobile computing and working from home pushed technology further to make computers faster and lighter, allowing the consumer to work remotely from anywhere.
HDI Technology is the leading reason for these transformations. Products do more, weigh less and are physically smaller. Specialty equipment, mini-components and thinner materials have allowed for electronics to shrink in size while expanding technology, quality and speed.
Key HDI BenefitsAs consumer demands change, so must technology. By using HDI technology, designers now have theoption to place more components on both sides of the raw PCB. Multiple via processes, including via in pad and blind via technology, allow designers more PCB real estate to place components that are smaller even closer together. Decreased component size and pitch allow for more I/O in smaller geometries. This means faster transmission of signals and a significant reduction in signal loss and crossing delays.
Via in Pad ProcessInspiration from surface mount technologies from the late 1980's has pushed the limits with BGA's, COBand CSP into smaller square surface inches. The via in pad process allows for vias to be placed within thesurface of the flat lands while using eight additional steps to complete this unique process. Specialty equipment and trained technicians follow the process closely to achieve the perfect hidden via.
Quality remains the most important factor for the consumer second to price. Using HDI technology during design, it is possible to reduce an 8 layer through-hole PCB to a 4 layer HDI microvia technology packed PCB. The wiring capabilities of a well-designed HDI 4 layer PCB can achieve the same or better functions as that of a standard 8 layer PCB.
Via-in-Pad technology shown .005 laser drill within .015 BGA capped and plated pads.
.005 via holes within .014 copper pads are filled, capped and plated over allowing for
small component placement.
