Solder mask comes in different media depending upon the demands of the application.

For this purpose, the space between the pads is often coated with a solder mask.

Solder mask is traditionally green but is now available in many colors.

Is the file the top solder mask, or the bottom copper layer, etc?

Construction requires a hole to be opened in the solder mask, exposing the copper trace.

Each double-sided board has a solder mask on both sides and hundreds of plated-through holes for your parts.

We do also have Black and Yellow which can make a nice contrast with different colours of Solder mask.

Corrosion products occurred on the solder mask contained higher concentrations of copper and chlorine.

A properly constructed bead is the same width as the trace and just enough to clear the surrounding solder mask.

PCBs use solder masks to prevent this from happening.

The trigger for the explosion was an MST-13 timer of the single solder mask variety.

Also the height of the solder mask should be lower than the pad height to avoid gasketing problems as shown.

Solder mask was green.

Once applied, openings must be made in the solder mask wherever components are soldered, which is accomplished using photolithography.

Areas that should not be soldered may be covered with solder resist (solder mask).

Soldering time averages one second per joint; stencils and solder masks may be eliminated from the circuit board to reduce manufacturing costs.

A technique has been described which opens up windows in the solder mask to create test points located directly on PCB tracks.

PCB vias that are tented (completely masked) were not removed from the solder mask printout.

The solder wets to the exposed metallic areas of the board (those not protected with solder mask), creating a reliable mechanical and electrical connection.

Dry film solder mask is similar to the dry film used to image the PWB for plating or etching.

The lowest-cost solder mask is epoxy liquid that is silkscreened through the pattern onto the PCB.

One of the most common solder resists used today is called "LPI" (liquid photoimageable solder mask).

Dual illumination systems optimize lighting for hard-to-detect defects in metal plating as well as in solder mask layer.

Epoxy resins are used to bond copper foil to circuit board substrates, and are a component of the solder mask on many circuit boards.

Surface tension causes the bead to have a curved surface and rise above the solder mask, where it solidifies into a Bead Probe.
