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…

Take advantage of the weak pound by choosing UK manufacturing


The current dollar exchange rate means the UK manufacturing is being helped by the weak pound and it is time to reconsider UK manufactured PCB’s. If you are sourcing products PCB’s in the Far East, the continuing weakness of the British Pound against the US dollar means overseas supply costs have increased significantly over the last few months. Weak pound is at lowest level since 1985 Since the Brexit Referendum, the British…

Routing Machine cutting PCBs

routing machine cutting PCBs ABL Circuits

CNC Routing Machine This is our CNC Routing Machine used for cutting out boards at the end of all the processes and we can leave them in a panel, like that with all sorts of complex shapes, sizes, angles, radiuses, gradients or we can fit them out with single circuits depending on what the customer prefers. They’re often left in the panel like that for ease of assembly. This one…

Tin stripping in PCB production

tin stripping in pcb production ABL Circuits

Tin Stripping The next part of the process is tin stripping. This strips off the tin that is now protecting our copper tracks. To do this we put it in the tin stripper which is a nitric acid based spray rinse machine conveyerised again which power washes off all the tin leaving the bare copper tracks which will be the finishing process of the bare board manufacture.
