What Neoplexus Tecnhologies does

Neoplexus Technologies is a Brazilian Electronics Manufacturing Services (EMS) provider offering printed circuit board assembly in both Through-Hole (PTH) and Surface-Mount Device (SMD) technologies, alongside cable harness assembly and electronic testing. Founded in 2009 and based in the São Paulo region, the company operates with a headcount of 11-50 employees and serves two structurally different customer segments: early-stage startups requiring prototype and small-batch runs, and national or multinational enterprises needing larger-volume production. The service mix covers the full build lifecycle from prototyping and small batches to large-volume production, with capabilities in cable harness assembly and what the company describes as "gigas de testes" (large-scale testing). Technical execution rests on conventional EMS processes — PTH and SMD placement lines, board-level testing, and harness fabrication — supplemented by a partner network of hardware and firmware developers that allows Neoplexus to deliver R&D services alongside manufacturing.

The company's commercial model is quote-based and project-driven, consistent with low-volume contract manufacturing. A turnkey supply chain offering bundles component sourcing from both domestic and imported suppliers, and a dedicated PTH-to-SMD migration service targets customers modernizing legacy through-hole designs. Quality and compliance credentials are self-attested at ISO 9000 and IPCA level. The go-to-market is sales-led and unusually lightweight for an industrial manufacturer: prospective customers engage via WhatsApp direct messaging rather than through traditional B2B sales processes, indicating a focus on reducing acquisition friction and serving long-tail, relationship-driven demand.

No funding rounds, acquisitions, leadership changes, or geographic expansions are disclosed. Revenue, customer logos, and segment-level economics are not provided, limiting visibility into commercial scale and trajectory. The single-source data footprint reflects a privately held, small-scale operation that has sustained operations for over 15 years without external capital or inorganic moves.

Direct peers

• MacroFab: Digital EMS platform offering PCB assembly, prototyping, and turnkey supply chain for startups through enterprise, with a cloud-based factory network. Overlaps directly with Neoplexus on EMS service scope (PCB assembly, prototyping, turnkey) while representing a more software-enabled operating model.
• Advanced Assembly: US quick-turn PCB assembly house specializing in SMT prototypes and small-batch production. Direct competitor in the prototype-to-small-volume segment of EMS that Neoplexus targets with its startup and small-batch services.
• Bittele Electronics: EMS provider offering PCB assembly (SMT and through-hole), turnkey component sourcing, and prototype-to-low-volume production. Matches Neoplexus on PTH/SMD capability and turnkey model, with a more offshore cost structure.
• PCBWay: Global PCB fabrication and assembly provider offering prototype to volume SMT assembly, turnkey component sourcing, and cable/harness assembly. Closely comparable to Neoplexus on the full assembly-plus-procurement stack, with a stronger digital storefront and international reach.
• Sunstone Circuits: US PCB fabrication and assembly provider offering prototype through production SMT assembly with online quoting. Comparable to Neoplexus on the prototype-to-volume PCB assembly continuum for small and mid-sized customers.
• Screaming Circuits: Prototype-focused PCB assembly house specializing in quick-turn, low-volume SMT and through-hole builds with online quoting and ordering. Comparable to Neoplexus's prototype/small-batch offering and online-style quote-based engagement, though with a more automated digital front end.
• Cal-Chip Electronics: US-based contract electronics manufacturer providing PCB assembly (PTH and SMD), prototyping through low-volume production, turnkey and consignment options, and cable/harness assembly. Highly comparable to Neoplexus across service mix, customer profile (startups through enterprise), and assembly techniques used.

Broad incumbents

• Jabil: Global tier-1 EMS provider offering PCB assembly, supply chain management, and full product manufacturing across multiple industries including industrial and automotive. Represents the scaled incumbent that competes with Neoplexus for multinational enterprise volume contracts but operates at vastly larger scale and broader scope.
• Flex (Flextronics): Global EMS giant providing end-to-end design, PCB assembly, supply chain, and manufacturing services across consumer, industrial, automotive, and healthcare. Comparable to Neoplexus in underlying capabilities but with global footprint, in-house design, and orders-of-magnitude larger scale.

Emerging players

• Tempo Automation: Software-driven quick-turn PCB assembly and prototyping service focused on speed and digital workflow for hardware startups. Partial overlap with Neoplexus on prototype NPI work for startup customers, with a stronger automation/digital stack.
