When you subject these transistors to maximum current and voltage, they carry out quick switching operations.

· Resonant

In the resonant mode, you find an LC circuit’s employment to influence the transistor’s current and voltage values.

Consequently, you find the transistor switching at zero current or voltage.

How does the DC-DC Converter PCB Compare with the Linear Regulator?

The linear regulator is an electronic feature you employ to produce a defined DC voltage.

You find the voltage produced is not dependent on the voltage from the input.

Additionally, the input voltage is independent of the resulting load emanating from a high-value input source with reduced stability.

You find this to be a result of the release of current and voltage excesses in the form of heat.

It follows that you can describe the linear regulator function as similar to that of the DC-DC converter PCB.

However, this is only when considering applications where the output voltage is lower than the input voltage.

You find DC-DC converter PCBs to cost more than linear regulators in select applications.

Nonetheless, technological advancement is bridging the cost gap between the two circuits.

Automated Optical Inspection

An automated optical inspection uses cameras to capture board details before making comparisons with the board’s blueprint.

You can employ a 2-D camera or a two-camera combination of 3-D design.

The comparison should match, and you should identify inconsistent circuit boards for rework or write them off.

By carrying out an automated optical inspection, you can highlight non-functional issues such as component misplacements and unsecured circuits.

Consequently, you can identify errors and faults before actually electrically testing the board.

As a result, you save on costs by identifying fabrication issues early on while they can be addressed.

Bed of Nails Test

It is prudent to follow up on an inspection procedure with an electrical test such as the bed of nails test.

Carrying out an inspection procedure before helps you identify faults that could otherwise be falsely attributed to electrical malfunctions.

In a bed of nails test, you have a tester formed of several aligned pins.

You use these pins to create contact points with your DC-DC converter PCB.

When you press down the DC-DC converter PCB on the bed of nails test kit, you create an electrical connection.
