Prototyping PCBs using a Laser System – LPKF ProtoLaser S

Prototyping PCBs at the press of a button

Getting your hands on prototype PCBs quickly is a crucial advantage in electronics development. This is what the new LPKF ProtoLaser S is all about. The laser system opens up a new dimension in in-house prototyping: it transfers the layout onto the PCB with unprecedented speed and precision – easily and with no chemicals.

LPKF laser system slashing development times

As circuit layouts become increasingly more complex, with the frequent involvement of numerous iteration steps and several prototypes, there is also increasing pressure to shorten development times. Companies that are prototyping PCBs in-house gain a vital advantage over the competition. They will not have to wait on external service providers. In the same time it takes to prepare an order for external prototype PCB production, the ProtoLaser S can transfer the complete circuit layout onto the PCB. This slashes development times and cuts time in the production pipeline. The confidential data also stays in-house and away from prying eyes.

Produce small batches on demand

Prototyping PCBs with the ProtoLaser S allows for maximum flexibility in design development. The high processing speed and the simple data handling also make it possible to produce customized small batches on demand. All of the usual PCB materials can be used.

Equipped for future needs

The revolutionary tool-less laser processing method can be used to produce lines and spaces, as well as corner radii, which far exceed today’s ultrafine technology standards. Process parameters for new materials can be easily established.

Decrease tooling times

PCBs are securely held on the integrated vacuum table – including thin and flexible substrates. The integrated software safely and simply converts the usual layout data formats into production data. Pre-set processing parameters for standard materials make operations even easier.

Fully automatic production

The optimal focus of the laser is adjusted automatically. No tool changes or other modifications are required during production. All that is required is loading new material or flipping the PCB material for double-sided projects. A camera uses fiducials to localize the position of the PCB and align the laser processing accordingly. Therefore prototyping PCBs that are double-sided and multilayer becomes a simple and precise manufacturing process.

Compact and safe

Prototyping PCBs with the ProtoLaser S is especially effective for laboratory use. It is compact and easy to operate. The hood protects the users from noise emissions, and prevents any accidental interference in the operational process. The laser switches off immediately when the hood is opened. The system is classified as Laser Class 1 when in operation.

Intuitive software operation

The software is designed for easy operation of the machine and the smooth import of the usual data formats such as Gerber or DXF files. A whole range of applications can be handled using the pre-set and customized profiles. The software also enables communication with other LPKF systems such as LPKF circuit board plotters.

Works with all types of PCB materials

The LPKF laser system is an excellent choice for prototyping PCBs in all types of PCB materials. Circuit layouts structured by laser The LPKF ProtoLaser S selectively ablates the conductive layer, usually copper, from the substrate. This cuts the insulation channels to precisely create the planned tracks and pad surfaces.

Areas of application

The ProtoLaser S is ideal for the efficient prototyping of complex digital and analogue circuits. It is the best solution for prototyping PCBs for HF and microwave in sizes up to 229 x 305 mm. The potential to produce highly precise geometries in almost any material makes the ProtoLaser S the perfect system for the production of antennas, filters, and numerous other applications which require precise, steep edge quality.

High repetition accuracy

The repeatability of the results far exceeds the ability of mechanical or chemical methods, which are also negatively affected by wear and process fluctuations. The ProtoLaser S guarantees constant properties even where many iteration steps are required, and for complete small batches.
