ECS Factory Tour 2007 – Making a Motherboard

Etching

Here the cleaned boards go through an Alignment Exposure Unit. This machine basically photographs both sides of the PCB, allowing closer inspections of the circuitry to be completed before etching. If they are approved they go on to the Etching process.

After the etching process is complete, the D/F lamination layer is removed and the PCB is rinsed once again in a machine like we just saw on the previous page.

After the sheets are cleaned they are starting to look like a motherboard! Here we can see that the sheets of PCB that we have been following actually have three micro-ATX motherboards on them. Having a hard time making them out?

Here is a closer look at one of the PCBs and as you can see it’s starting to look like something computer enthusiasts would understand!
