PCB Design

The details are not the details. They make the design

~ Charles Eames

We know how much the details matter. That’s why we created Dena Design Services: we worry about the details so you don’t have to. 

We’ve taken our exacting standards and focus on quality craftsmanship to create a complete, end-to-end service. We take you from concept to product to design in a single sprint, accelerating your time to market.

PCB Design

First Concept, Then Design

Reduce costly errors and get to market faster with our early stage design services. Our dedicated Dena Design Services team works with you to collaboratively develop concepts and create more effective designs for production.

Our industry-focused insights decrease overall production time and reduce manufacturing costs by creating more exacting specifications for your products, accelerating your ability to respond to ever-changing market needs.

We know it’s the little things that count. See how we’ve helped numerous companies get ahead by focusing on the right details: Get inspired by our Case Studies.

Design Verification

Dena Design Services offers PCB Design Verification for Manufacturing (DFM) and Design for Assembly (DFA) to enhance the success rate of your designs. Our experienced team reviews and provides recommendations to increase yield and reduce production costs.

Additionally, we offer this service to all of our PCB Assembly clients to help ensure the finished product has the impact it needs to succeed.

According to independent research from The Aberdeen Group, customers who use Mentor Graphics Valor NPI to verify PCB designs experience:

PCB Assembly

Fully Automated

SMT Assembly-Line

Dena Technologies has a fully automated SMT production line. SMEMA connections (Surface Mount Equipment Manufacturers Association) control the passage of boards from one machine to another. The major pieces of equipment are separated by various conveyor units.

Begins at the automatic magazine board loader

Dena’s Board Loader with two full magazines (100 panels)

Bare boards are loaded into magazines

Up to 50 panels can fit inside each magazine. When running the second side of double-sided PCB’s, if any of the components are especially tall, the loader can be configured to skip empty slots in the magazine to make room for the tall components.

Boards inside the loader magazine

Two magazines loaded at once

Full magazines are placed on the lower shelf. The magazine is conveyed into the lift section next to the solder paste printer. As each board is taken, the magazine is lifted in steps. When the magazine is empty, it is conveyed backward onto the top shelf and the next full magazine is conveyed into the lift. The loader can hold three magazines at a time, but only two of them can be filled.

Ends with occasional spot inspections

Dena’s lift-gate conveyor allows access to the rear of the PNP machine

A lift gate which allows the operator to easily walk around

After the printer is a lift gate which allows the operator to easily walk around the back of the pick and place machine to access the rear feeders. Lifting the gate will automatically prevent the printer from sending boards out.

Dena’s in-line inspection station

Our pick and place machine does an absolutely exceptional job

However exceptional, it is still necessary to perform first article inspections and occasional spot inspections. Sometimes this station is used to place unusual components which cannot be loaded onto the pick and place machine. The station has a switch to either let boards pass through or stop them until the inspector presses the pass button to release boards to the reflow oven.

Solder paste composition varies per PCB application. Read about it in our industry specific Case Studies
Solder Paste Printing

95% of SMT defects are caused by poor paste printing

  • 2D inspections of all solder-paste deposits to control solder-joint failures
  • The SJ Inno Tech HP-520S Solder Paste Stencil Printers, are our equipment of choice

Selective Soldering

We use nitrogen jets to avoid ‘Solder Bridging’ problems during assembly

  • We strictly enforce a 3mm clearance between through-hole pads and SMT to avoid solder bead
  • We use various nozzles which allows to utilize Wave Soldering techniques too
  • The KISS-102 Selective Solder Machines are our equipment of choice

KISS-102

The system is very easy to set up and operate. The screen displays an image of the bottom of the panel. You simply draw out on the image where you want the bead of solder to go. We have different sized nozzles including long nozzles which allow the machine to operate effectively as a wave solder machine.

  • The system operates with a nitrogen jet to prevent bridging
  • Minimum panel size: 2″ x 2″ (50 x 50mm)
  • Maximum panel size: 16″ x 16″ (400 x 400mm)
We are equipped to support up to 15,000 components per hour

Wire Stripping, Cutting & Soldering for PCB Assembly

Dena has a streamlined process to tin, crimp, solder and/or plug your wires onto your PCB assembly.

  • Our machine has the capability to process two wires simultaneously, provided that they are the same length with the same stripping setup and not already twisted.
  • Our machine can be used to remove the outer jacket from multi-conductor cable.

  • Our solder pot is used to tin the ends of the wires if necessary or we can crimp contacts on to the ends of the wires using our pneumatic crimping tool. This system uses standard interchangeable dies.
  • Some crimp contact manufacturers such as Hirose only sell expensive custom tooling (Please be careful when specifying crimp connectors that the required tool is readily available and inexpensive. Attempting to crimp contacts without using the specified tool may result in unreliable, poor quality connections)
  • The wires can then be soldered or plugged onto your PCB assembly.
