Charlie Lewis celebrates 30 years at ABL Circuits

Charlie Lewis 30 year anniversary at ABL Circuits

And 40 years in the PCB industry UK, May 2, 2018 – Charlie Lewis, General Manager of ABL Circuits, has been a valued member of the ABL Circuits team since 1988. Charlie joined the Printed Circuit Board (PCB) industry in March 1978 as a 16 year-old school leaver. He rose through the ranks at Editron Circuits in Letchworth for the first 10 years of his career, gaining experience in profiling,…

Who invented Printed Circuit Boards (PCBs)?

inventor of Printed Circuit Board uk

The invention of printed circuit boards (PCBs) is credited to Paul Eisler. Paul Eisler, was a trained electrical engineer in Vienna who came to the UK in 1936 as a refugee. By that time he had work experience in the radio as well as the printing industry and he had patented a number of inventions. After a few experiments, he used his combined experience to construct a radio set with…

How many layers does the record-holding Multilayer PCB hold?

Multilayer PCB ABL Circuits

The Guinness book of records reports that the most layers in a Multilayer PCB is 129 (to date 2017). It was created in Japan in 2012 for use in electronic devices, such as computers and cell phones. 3 Steps to Decide the Number of Layers in Multilayer PCBs: Calculations. With PCB design tools, some basic parameters should be calculated first including grid number, network density, average pin density, operation frequency…

Who is pioneering the art of Printed Circuit Boards (PCB’s)?

PCB Art of printed circuit boards ABL Circuits

Who is pioneering the art of Printed Circuit Boards (PCB’s)? One of the world’s pioneering artists who recycles PCB’s into works of art is Steven Rodrig, a former computer and electronic equipment repair man, born in Cuba 1963. His PCB artworks have interesting titles such as “Dragonfly on limited time to transfer data” or “Data spider” to refer to the PCB creations he makes. His work frequently appears on social…

What is a Printed Circuit Board Pad?

Printed Circuit Board Pad

The Printed Circuit Board Pad is a small metallised area (usually copper) to which electronic components are connected or attached. You can think of a pad as a piece of copper where the pins of the component are mechanically supported and soldered. There are 2 types of pads; thru-hole and smd (surface mount). Thru-hole pads are intended for introducing the pins of the components, so they can be soldered from…

Why are multilayer PCBs so popular?

Multilayer PCBs for ABL Circuits

Multilayer PCBs offer more complexity and capacity on a smaller footprint, thus saving space and weight whilst offering increased functionality. This is what makes them so popular in modern electronics. The PCBs are multiple double-side boards that are bound together with alternating insulating materials to separate them. Drill holes between layers must be executed with great care and precision. Conductors on different layers are connected using vias which mean that…

Why are Printed Circuit Boards green?

Why are PCBs green? ABL Circuits

Did you know that the vast majority of PCB’s are green? But, why are printed circuit boards green? It is due to the solder mask, which protects the copper circuits printed on the fibre glass core to prevent short circuits, soldering errors, etc. The colour of the solder mask gives the board its appearance. Why are printed circuit boards green? There are different theories on why it is traditionally green…

ABL’s reverse engineering PCB expertise

Reverse engineering PCBs - ABL Circuits

As many assets on oil and gas rigs are ageing, there is a need for retrofitting parts of the system. ABL took on the challenge of recreating PCBs to the exact specifications drawn up for an oil rig over 30 years ago using their reverse engineering PCB expertise. In total, 17 different types of replacement Printed Circuit Boards needed reverse engineering to replace the rack-mounted legacy boards in the control…

What are printed circuit boards made of?

What are Printed Circuit Boards made of

A printed circuit board (PCB) consists of conductive and non-conductive layers bonded together to make one whole. The materials for a PCB can differ depending on their purpose and client needs. For example, a double sided PCB (also known as a 2-layer board) comprises: A core layer made of glass fibre reinforced epoxy resin; this provides a solid, rigid and non-conductive support layer, generally referred to as FR4 On each…
