     •In this section, we will look at some of the equipment that is used in modern PCB production.

  Each development stage is carried out by a dedicated piece of equipment – which may form part of an assembly line.

  Depending on your application, note that some stages may be missing here. For instance, a tinning stage is often included after etching to reduce copper layer oxidation. A multi-layer PCB, too, requires a lamination stage to join the layers.

  A raster plotter from Mega Electronics serves as a replacement to the photoplotter described earlier. This plotter is capable of creating a 5 micron spot.

  A laminator is used to apply the photoresist layer to the PCB. This laminator is from Mega Electronics.

  There are many different sorts of etching, developing, and stripping setups. This one is from Mega Electronics and is a unit that sprays the chemicals over board panels, mounted inside.

  Again from Mega Electronics, units such as this “Production Line” can be used to combine the chemical stages into a convenient unit. The operator is responsible for forwarding the PCB through the stages.

  Etch-resist, solder masks, parts placement silkscreen legends, and even solder paste can applied to a PCB using silkscreen printing technology.
