ABL Circuits PCB Manufacture Molten Solder

ABL Circuits PCB Manufacture Molten Solder

ABL Circuits PCB Manufacture Molten Solder Once the solder resist ink is cured the panels are then either hot air solder levelled, which involves emersing the whole panel in a liquid bath of molten solder, and as the panel is withdrawn from the bath, a blast of hot air blows out all the excess solder leaving the holes perfectly smooth and clean and all the surface mount pads perfectly flat…

ABL Circuits PCB Manufacture Solder Resist Ink

ABL Circuits PCB Manufacture Solder Resist Ink

ABL Circuits PCB Manufacture Solder Resist Ink The panels are then flooded with a photo image PCB manufacture solder resist ink and partly cured to be touch dry and they are then, using the same tooling process used earlier, the solder resist photography is laid over the tooling pins and exposed and then developed using the same process as earlier, and to give the solder resist pattern on the board.…

ABL Circuits PCB Manufacture Removing Tin

ABL Circuits PCB Manufacture Removing Tin

ABL Circuits PCB Manufacture Removing Tin Once etched the panels are dried and inspected and are passed through a tin stripping machine containing nitric acid which removes all of the protected tin that is on the copper tracks leaving the panel, bare fibre glass with the copper tracks that will be the final board.

ABL Circuits PCB Manufacture Etching Machine

ABL Circuits PCB Manufacture Etching Machine

ABL Circuits PCB Manufacture Etching Machine The panels are then passed through a conveyorised PCB Manufacture etching machine which contains an amonicon edge solution which sprays the panel to remove all of the copper areas that are not protected by tin, leaving bare fibre glass and the tracks that you want keep protected by the tin coating.

ABL Circuits PCB Manufacture Tin Plating

ABL Circuits PCB Manufacturing Tin Plating

ABL Circuits PCB Manufacture Tin Plating The next process along the plating line is to protect all the copper areas that you want to keep, which is the copper you can see, with tin. This is not the tin that is going to be on the board at the end of the process, it is there purely to protect the copper tracks from the etching process later on. So once…

ABL Circuits PCB Manufacture Electrolysis

ABL Circuits PCB Manufacturing Process Electrolysis

ABL Circuits PCB Manufacture Electrolysis Here is a panel that has been laminated and exposed and developed. You may be able to see the black carbon down the holes from the shadow process earlier, and that gives the electrical conductivity between the two sides of the board. So the next process is to plate copper over the holes and over the whole panel so that all the copper areas that…

ABL Circuits PCB Manufacture Developing

ABL Circuits PCB Manufacturing Process Developing

ABL Circuits PCB Manufacture Developing The next stage is to pass the panel, which has been exposed, through a conveyorised developing machine and this rinses off all of the areas that haven’t been exposed to the UV light.

ABL Circuits PCB Manufacture UV Exposure

ABL Circuits PCB Manufacturing UV Exposure

ABL Circuits PCB Manufacturing UV Exposure The panel is then vacuumed down in the exposure unit and exposed for a short time and the black and clear film will only allow the UV light to penetrate through the clear areas and this gives you your image of your tracking on the panel both sides.

ABL Circuits PCB Manufacture Photo Plots

ABL Circuits PCB Manufacture Photo Plots

ABL Circuits PCB Manufacture Photo Plots Once the panels are laminated, which is done in the yellow room because the film is UV sensitive, the photo plots which represent the component side and the track side, both have precision tooling holes punched in the field for locating on to the panel. These are positioned on a tooling pin and clamped down and the whole panel is put into the exposure…

ABL Circuits PCB Manufacture Lamination

ABL Circuits PCB Manufacture Lamination

ABL Circuits PCB Manufacture Lamination Once through the conveyorised shadow process the boards come out dry and perfectly clean and the copper is bright copper but has carbon down the holes and the next process is to pass it through the laminating machine which puts a blue photosensitive UV film onto either side of the panel.
