What is the use of the silk screen layer in PCB?
The silkscreen layer is the top layer of the PCB and serves as a reference indicator for placing components on the PCB. The graphics and text on PCB a circuit board is usually printed with a permanent non-conductive epoxy ink.
What is a silkscreen and what purpose does it serve in a circuit board design?
Silkscreen is a layer that uses ink traces to identify all the PCB board components, test points, parts of the PCB, warning symbols, logos and marks etc. These shapes, numbers, and letters really aren’t some new language. They can also communicate the function of each of the pins.
When to use a silkscreen on a PCB board?
The silkscreen is used to specify useful information on the PCB board that can help/assist users during assembly. It is used to mark component values, part numbers, test points, polarity etc. What is the purpose of using a silkscreen layer? The silkscreen is not applied to PCB boards by default.
What kind of screen do you need for silk screen?
For traditional silk-screening you require a polyester screen stretched on aluminum frames, a laser photo plotter, spray developer and curing ovens. There are three basic ways to apply silkscreen. 1. Manual Screen-printing
Can a silk screen be used on a solder side?
This silkscreen is usually applied on the component side; however using silkscreen on the solder side is also not uncommon. But this may increase the cost. Essentially a detailed PCB silkscreen can help both the manufacturer and the engineer to locate and identify all the components.
How is acrylic ink cured on silk screen?
The ink is cured with UV light as it is printed. It should be noted though that the acrylic ink does not cure on boards with silver finishes. A properly designed silk-screen can prove to be highly useful as it can reduce the chance of error and can reduce time taken to spot the error.
