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.

PCB Etching process

PCB Etching process ABL Circuits pcb manufacture

PCB Panels So here we can see the PCB panels coming out of the etcher in the PCB etching process and as you can see all the copper has been spray rinsed off leaving us our tracks with our tin on top, both sides, perfectly done.

Bespoke Circuit Boards Sparks Interest

classic car bespoke circuit boards abl circuits

ABL Circuits were approached when a supplier of tuning equipment for cars and car modifications was looking for a new and reliable supplier for bespoke circuit boards. The main requirement was to create a performance enhancing booster amplifier for a V8 engine ignition system. Bespoke Circuit Boards ABL Circuits took on the task to reverse engineer the old design of the dual-timer power amplifier and rebuilt a superior version. Working…

Removing the film on the PCB

removing PCB film at ABL Circuits PCB Manufacture and Design

Removing the PCB Film So, after the tin plating, the next part of the process is removing PCB film. The blue film as you can see here which protects the copper underneath and gives you your image of the circuitry on the panel. But that’s only required for this stage because now we have the copper tracks that we want to keep eventually protected by the tin that we’ve just…

PCB tin plating stage

PCB Tin plating manufacture ABL Circuits

For a budgetary board PCB Tin Plating So this is the next stage in the process of producing a budgetary board, it’s PCB tin plating, that’s plated on top of the copper purely to protect it further down the process. That’s all that does, so that’s not the tin that’s on the board at the end, that’s purely to protect the copper tracks that are underneath the tin when they…

PCB immersion in copper sulphate solution

PCB immersion at ABL Circuits

Plated Through Board PCB immersion in copper sulphate solution The PCB immersion is the most important part of the process of making a Plated Through Board. The panel is immersed on a jig in a Copper Sulphate solution and is plated onto the surface and down the holes electrolitically by applying current to this which attracts the Copper which is held in these bags here which are full of Copper…

PCB CNC drilling machine

PCB CNC drilling machine at ABL Circuits

Fully automatic CNC drilling machine This is our CNC Drilling machine, it is fully automatic, it can run through the night un-manned, it is auto load, 23 different stacks or even 23 different jobs if needed and we have 500 different tools at the front ranging in size from 0.3 of a mm (which gives us a 0.2mm hole after plating) to 6.5mm. Anything larger than that then we round…

ABL Circuits miniature oscillator ABL Circuits were approached by an antenna manufacturer to create, manufacture and test a circuit board for an Miniature Oscillator used to train amateur radio operators to gain their intermediate licence. Users of AM radio frequency undertake self-training and part of the training includes the assembly and operation of an miniature oscillator. This is used to convert direct current from a power supply to an alternating…
