You will find many different types of printed circuit boards that could fall under the distinction of “advanced PCB”. The assortment of boards that could fit the distinction of boards include those that are actually high density interconnect (HDI), controlled impedance, aluminum clad, flex, rigid flex, blind-and-buried or any combination of these. Nearly every industry type has some type of (PCB) which will fit this description. Every one of these circuit board types has difficulties associated with design, assembly and fabrication. Many circuit boards that would’ve been considered advanced PCB adecade ago won’t make the show today which shows that this term is actually dynamic.
High density PCB seem to be at the top of the checklist when advanced PCB are discussed. Projects continue to get more complicated and the consumer expects the measurements of its products to reduce which motivates the need for circuit boards that are more densely populated. Designers are forced to packing more and more circuitry into less and less space. This creates significant issues for both the PCB fabricators and also the CB assemblers. The CB fabricators are working with the issues of even shrinking trace widths, blind-and-buried vias, via in pad, as well as decreased annular rings.
The high power LED market has increased the demand for advanced PCBs clad with aluminum. These specialized CB are created to help the transfer of high temperatures away from the LEDs. PCB fabrication are a combination of printed circuit and heatsink. Horizon Printed Circuits are able to help design these advanced PCB as well as fab and make them.
Controlled impedance has become more the rule then the exception and still it qualifies as a sort of innovative printed circuit board because of the level of care needed to get consistently exact results. The layout is just the first challenge. Printed circuit rii fab needs to be completed with a properly understood process. The etching must be accomplished without under or over etching. The substrate is also the dielectric and must be kept to a reasonable tolerance to ensure the expected impedance.
A significant percentage of items which are new have been designed to use rigid flex PCBs. These CB put together rigid substrates with flexible material to form boards that are flat and rigid in some areas and adaptable in others. Many products use these CB to create a 3 dimensional assemblies which are both electrical and mechanical.
The drive within the PCB trade is in the path of a lot more complex advanced PCB. New advancements in this specific place make our products scaled-down, more capable and easier to assemble.
