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!

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.

Electronic Interconnect offers an Engineering Service in designing a multilayered controlled-impedance stackup

Advancements in technology have driven PCB Designers & Engineers to seek improvements in system development & develop strategies to overcome signal communication issues. To this end, it has become increasingly evident that a solid & sound PCB design can greatly mitigate such issues and ultimately lead to better signal integrity.

If your 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 investigate & calculate the best trace-width, trace-space, layer-to-layer spacing, as well as which PCB materials should be used.

We are taking this opportunity to announce that Electronic Interconnect has begun providing an Engineering Service in designing a multilayered controlled-impedance stackup to fit your design targets. You can either consult us before starting the design or if you've already finished the PCB Layout, then we can take the information from your Gerber data & design a stackup to meet the desired impedance goals. Our extensive PCB fabrication knowledge coupled with the awareness of our shops tolerances helps us deliver stackup solutions which can best fit your controlled-impedance designs.

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.
