Example Products

We have assembled a variety of products including security system, robotic equipments controller, audio/video system, LCD display driver, animal pulse and blood pressure monitor, surgical monitor for the Vet-clinic, and ultrahigh frequency circuit board for satellite communication that sold to the US government.

Circuit board with Melf components, SMT component size 402 to C-case electrolytic capacitor, and components are installed on both side of the board and mixed with standard thru-hole on the top side.

Multi-layer board with component size 603 and up, IC TQFP @ 12 mil. pitch, and components are installed on both sides.

Multi-layer board with SMT size 805 and up to high current power components and mixed with several different types of connector.

Our Services

At M-Tronic, we have the capability to work with single sided, double sided and multi-layer circuit boards. PCB size ranges from 1/2 x 1 inch up to 20 inches width, and chip component sizes range from 402 and up. All applications can be mix with standard through hole component and install on both side of the circuit board. In addition to our PCB capabilities, we also work with cables and wiring harnesses assemblies that involves wires stripping, tinning, crimping and soldering.

We take pride in our competitive low cost and high quality products. We have provided the following services to our customers and have received excellent feedback for our outstanding services, quality products, best prices and meeting customer’s requirement.

  • PCB design and layout to meet customer’s specifications
  • Schematic Design, Library development
  • Engineering documentation
  • Prototype builds
  • Surface mount PCB assembly. “Fine Pitch” Capabilities
  • Thru-hole printed circuit board assembly
  • Low to medium volume production
  • Mechanical, electro-mechanical assembly, and packaging
  • Complete functional testing on the product we built with our customer’s test equipment
  • Turnkey contracting manufacture
  • Rework printed circuit board assemblies to meet customer’s requirement.
  • (Installation or removal: BGA, CSP, µBGA, TQFP, QFP, PLCC, SOIC, TSOP, SOL, SOT, Chips and thru-hole components)
  • Cables and wiring harnesses assemblies
  • Lead-free production capabilities

Immediately following a client order, we procure and inspect all require components. We methodize drawings and color coded SMT components for automate pick and place and conventional thru-hole for manual placement. Component placement, reflowing, soldering, cleaning and assemblies are performed in our facility to complete the manufacturing cycle. We performed quality control, inspection and testing at appropriate steps during the manufacturing process while utilizing comprehensive Statistical Process Control (SPC). We performed 1% AQL (audit) at a final step prior to packaging. Completed assemblies are marked date-coded and anti-static packaged for shipment
