Rework / Repair Services

Precision Laser Micro Machining, Marking, Scoring, and TaggingLaser micro machining on PCBs requires that materials are either cut through, partially cut through, scored or marked in a very precise and repeatable fashion. BEST has the capability to precisely machine your PCB assemblies and components for marking, rework or production requirements.

BEST's laser tools are micro-machining systems with a broad range of capabilities. BEST has a variety of laser micro machining sources including CO2, YAG and green laser source with a variety of beam delivery and machining tables. Feature sizes down to 10 microns are possible with these systems. Materials which can be processed by BEST for laser micro machining include but are not limited to: plastics, glass, wood, thin films, metals, ceramic and other organic materials. We can take in a variety of file types including GERBERS, AUTOCAD, jpegs, tiff and giff and other file types.

Laser Marking PCB's - Laser ScoringLaser Marking PCB's - Laser ScoringPart Marking and DeMarking

BEST laser systems can both mark and demark letters, symbols and graphics on boards, components and housings. Marking of parts may need to occur for tracking purposes while the demarking of parts may need to occur for protection of intellectual property.

PCB Marking

Marking serial numbers or other images on PCB

Our laser systems can be used to quickly and permanently mark alphanumeric, logos, and bar codes into a variety of materials including PCBs, components including wires and cables and metal housings which have been coated or anodized.

De-paneling

Lasers can be used to depanel individual PCBs from panels. In addition laser depaneling is often used when very tight tolerances are required for PCBs such as when there is very little room in an enclosure that the board is fitting in to. For the ioT applications very small boards in a variety of non-traditional shapes may need to be precisely cut to fit into enclosures.

Cutting

A variety of polyimide shapes can be cut for use in the wave soldering operation. While standard shapes such as dots and squares are used for wave soldering, insulating circuit board against high temperature, BEST can produce custom shapes to customer specifications for these same purposes. In addition, shapes can be cut from a variety of stainless steel sheets or even glass or plastic sheets.


Laser Mask RemovalLaser Mask Removal
Selective Mask Removal

Defining new pads for rework through selective mask removal on PCB's.

There are instances when a rework has to be performed when solder mask needs to be removed selectively from different portions of the PCB.  Laser methods have the advantage of control, cleanliness and precision over other traditional mask scraping techniques such as mask scraping and micro abrasion.

Cleaning

Lasers can clean conductive pads of many types of materials.  This method is far cleaner and neater than mechanical or chemical methods.

Flex Circuit Material Removal
Flexible circuits can be laser drilled or laser skived to produce through vias, blind vias or to remove dielectric material and expose conductive pads or fingers.

Laser Stripping of insulation from wiringLaser Stripping of insulation from wiringStripping of insulation on wires and ribbon cable

Selective window pane stripping of ribbon cable

Since the wavelength of the CO2 laser is tuned for plastics and polymers the stripping of insulation from wire or ribbon cable is a natural application for this type of laser. The metal wire strands serve to block the rays without nicking or marring the surface of the metal strands. For more precise insulation stripping the 355nm YAG laser can achieve very precise stripping or window pane stripping of cables.

BEST is your source for micro machining in the electronics industry. We have many years of experience and many different laser sources to draw from. We know how to handle electronic assemblies as we also provide PCB rework and repair services. From precision pad definition to part marking or even board depanelizing for someone producing electronics or sub-assemblies call BEST to see how we can assist you in getting the project done.
