FLEX AND RIGID-FLEX LAYER STACKUP TYPES

in

There are a number of standard stackups available for flex and rigid-flex circuits, referred to as Types. These are summarized below.   Type 1 – Single Layer Single-sided flexible wiring containing one conductive layer and one or two polyimide outer cover layers. One conductive layer, either laminated between two insulating layers or uncovered on one side. […]

Rigid-Flex circuit boards Design

in

Flexible circuit technology was initially developed for the space program to save space and weight. They are popular today as they not only save space and weight – making them ideal for portable devices such as mobile phones and tablets – they can also: reduce packaging complexity by substantially reducing the need for interconnect wiring; […]

2017’s effect that Trump will make on electronics manufacturing?

in

I think it’s very interesting but important topic to discuss about the breaking year and possible changes. What could a Trump effect look like in 2017? I think there are several positives: • A president who is pro-manufacturing. We haven’t had a champion of manufacturing in the White House in a long time … decades, […]

PCB Layout to design process

in

PCB design equipment In the early days of PCBs, the design and layout was undertaken manually using tape that was placed onto a translucent film. These PCB designs were normally four times the required size and they were photographically reduced onto a 1:1 film for the PCB production process. Nowadays the PCB design process has […]

PCB Surface Finish & Conformal Coating

in

HASL /Electroless Nickel Immersion Gold (ENIG) Refer to past projects, the most popular surface finish choices of customer is HASL,as its low cost and robust, fundamental changes in the PCB industry—namely, the rise complex surface mount technology—have exposed its shortcomings. HASL leaves uneven surfaces and is not suitable for fine pitch components. Although it does come […]
