Manufacturing Equipment
A complete SMT and through-hole line under one roof in Middletown, Ohio.
Our 10,000 sq ft facility runs a full domestic PCB assembly line — from solder paste printing through placement, reflow, selective soldering, inspection, and cleaning — all in-house. Nothing gets shipped out mid-process, which is how we hold quick-turn schedules without giving up control of quality. We handle high-mix and high-volume work with no minimum order, from a single prototype to a full production run.

Solder Paste Printing
Every reliable assembly starts with accurate paste deposition. Our MPM Momentum II 100 lays down consistent, repeatable paste application across fine-pitch and high-density boards, with the process control to keep first-pass yields high on complex layouts.
Surface Mount Placement
Our Yamaha I-PULSE M20 handles high-speed, high-accuracy placement across a wide component range. The 6-head, 2-theta configuration and tray feeder let us run both high-mix prototype work and high-volume production on the same line — versatility that matters when your program moves from prototype to production without changing vendors.
Reflow Soldering
The Heller 1809 MK5 gives us precise thermal control across the full profile, supporting both lead-free and standard processes. That flexibility means we can meet the regulatory and reliability requirements of demanding sectors — including medical and automotive — with strong, uniform solder joints on every board.
Selective & Through-Hole Soldering
For through-hole and mixed-technology assemblies, our ERSA VERSAFLOW 3/35 delivers precise, repeatable selective soldering. Where a board calls for hand work, rework, or special operations, it’s handled by soldering technicians with 30+ years of experience, IPC J-STD-001 certified. High-reliability connections, whether the run is automated or by hand.
Inspection & Quality Control
Reliability is verified, not assumed. Automated optical inspection catches placement and solder defects across the board surface, while Dage X-ray provides non-destructive inspection of hidden joints — BGAs, QFNs, and other components you can’t check by eye. On mission-critical assemblies, that’s the difference between a board that passes and a board that’s proven.
Cleaning & Protective Treatments
De-ionized water cleaning removes flux residue and contaminants that cause long-term field failures, protecting assemblies bound for demanding environments. Clean boards are reliable boards — especially where conformal coating or long service life is on the line.
Built Here. Built Right. Built on Schedule.
A complete line, skilled certified technicians, and domestic control of every stage — that’s how Adonai delivers high-reliability PCB assembly on quick-turn timelines.
