Printed Circuit Boards - IPC Netlist Comparison

Most PCB design software have the ability to export out not only Gerber data for fabrication, but also Netlist information. This Netlist is exported out in the popular IPC-365-A format.

Through our years of experience, we highly recommend asking your board-shop if they have the ability to compare your Gerber data with an IPC Netlist. This comparison ensures that the Gerber data matches the Netlist in your CAD software, avoiding any surprises that may have been caused through export issues or import issues from the fabrication shops CAM software. In the end, this provides an excellent reliability check so that corrections can be made and precious time is not wasted in extra design revisions.

Electronic Interconnect offers full IPC-365-A Netlist comparison support. For more information on PCB design visit our website.

PCB Fabrication and Controlled Impedance Stackups

Advancements in technology have driven PCB Designers & Engineers to seek improvements in system development & develop strategies to overcome signal communication issues.

If your electronics design requires specific impedance properties, for example a differential impedance of 90 ohms, & you need to design the PCB which can meet this criteria, then you'll need to research & calculate the best trace-width, trace-space, layer-to-layer spacing, as well as which PCB materials should be used. Keep in mind that there are certain tolerances encountered at each stage during PCB fabrication: the trace etching tolerances, the material thickness tolerances, as well as the copper finish tolerances.

PCB Arrays & Panels

The terms Array and Panel have been used interchangeably by various sectors. The PCB Fabrication industry normally uses the term Array to mean a pallet which contains multiple copies of the same circuit board.

At Electronic Interconnect, we design Arrays daily to meet the best yields of our PCB fabrication processes, and to meet the requirements of our customers. We can design with V-Scoring parameters, CNC Routing parameters, as well as a combination of both of these processes. By engineering PCB Arrays at our location, we are able to not only pass on the savings to our customers, but we also use our years of experience to design Arrays to result in trouble-free Assembly after fabrication!

Flexible PCBs

Flexible PCBs are relied upon for their physical ability to contract & expand for specialized products. These types of thin PCBs are used in a variety of products, such as automotive instrument panels, computer disk drives, medical controls, and telecommunication systems. Electronic Interconnect manufactures Flex & Rigid-Flex PCBs through our ISO compliant processes; for more information please visit http://www.eiconnect.com/techarticle_detail.aspx?b=4

EZ Amp - an op-amp experimenter board

The EZ Amp provides a convenient manner in which to experiment with operational amplifiers and to prototype circuit applications using them. Circuit patterns are provided for mounting op-amps that use a 14-pin DIP package. This includes a very large selection of standard part types.

In electronic prototyping, it is convenient to have the use of some mechanism to add circuits in a non-permanent manner, for testing. There exist many so-called “prototyping boards”, consisting of a sea of push-pin contacts that allow a circuit to be built in a very temporary manner.

Although prototyping boards are useful tools, they do not provide suitable connections for sensitive circuits involving amplifiers. Poor quality contacts and long lead wires may negatively affect the performance of the circuit. Even when the prototyping board provides adequate technical performance, it is not acceptable for inclusion as a design element for higher level prototyping.

The EZ-Amp provides a new step between “haywiring” and the final circuit. It can be used to breadboard multiple channels of analog signal conditioning in a manner suitable for all but the final step of packaging.

PowerLink PLPCB for Thermal Management Applications

Electronic Interconnect (EI), a leading manufacturer of printed circuit boards and provider of PCB engineering and design services, announces the availability of Powerlink PLPCB constructions for electronic assemblies where thermal management (heat dissipation) capabilities are desired.

PowerLink technology enables power and control circuits, both heavy copper and standard copper, to reside on the same layer with interconnection between the circuits. Bus bars with multi-copper weights handle the heat dissipation in the PCB, enabling extended PCB life and safety in overall functioning. The bus bars allow heat to dissipate more efficiently due to their high surface area to cross-sectional area ratio.

Electronic Interconnect Offers Direct Thermal Exchange (DTE) Configurations for LED Assemblies

Direct Thermal Exchange (DTE) design in printed circuit boards intended for LED arrays provides a direct thermal path to the base metal of the assembly, allowing the high-power LEDs to dissipate heat effectively, extending their working life and safety in overall functioning.

Electronic Interconnect (EI), a leading provider of printed circuit boards and PCB engineering and design services, now offers Direct Thermal Exchange for LEDs. Thermal Management designs and engineering are an area of specialization and focus for EI.

“DTE enables a very fast rather of thermal transfer through the LTE pad,” Pratish Patel, President, said in making the announcement. “This is an important enabling technology for LED-bearing circuits, especially those intended for outdoor lighting and emergency vehicles where heat dissipation is an ever-increasing concern as the technology of high-power LEDs advances.”
