SMG Global Circuits, a provider of PCB manufacturing and fabrication services, offering a range of circuit board technologies, finishing processes, and production capabilities for diverse electronic applications, offers a range of PCB finishing capabilities designed to protect exposed copper circuitry across printed circuit boards. The company supports customized panel sizes with finished copper thicknesses from 1 oz. to 5 oz. and minimum conductor space and width requirements of 0.004 inches.

The company offers several standard PCB finishing materials to address different manufacturing and application requirements. Tin/Lead HASL is available as a widely used surface finish that reduces costs and can be repaired when needed. For lead-free applications, SMG Global offers Lead-Free HASL-SN100, which meets RoHS requirements while providing a long shelf life and a cost-effective finishing option.

The finish is described as a long-lasting coating option and is suitable for projects that require plated through holes. The company further offers Immersion Silver to IPC-4553 standards as an alternative to ENIG, combining RoHS compliance with a cost-effective finishing solution. Additional finishing options offered by the company include Gold Tab Plating for applications requiring gold-plated contact areas.

Beyond standard finishes, SMG Global offers alternative PCB surface coatings. These include Enthone OSP-Entek Plus, an organically produced surface finish that provides an eco-friendly and non-lead option for printed circuit boards. The company also offers Immersion White Tin, which can be processed to produce flat and uniform surfaces, and Full Body Hard Gold, a lead-free finish that provides a durable and long-lasting surface for printed circuit boards.

In addition to surface finishes, SMG Global offers solder mask and silk screen services. Available options include Solder Mask Over Bare Copper (SMOBC) and LPI Solder Mask and Silk Screen configurations. The company provides multiple color and customization options, with a minimum solder mask pad clearance of 6 mil and a minimum solder mask dam of 3 mil.
