Multiple iterations within a single order

DeltaProto B.V. uses the image below to illustrate that our unique capability for multiple iterations within a single order not only delivers speed, but often also a cost advantage.

Small or large change? No problem, iterate quickly on your product design to accelerate your total development time.

The raw PCB design files, ready for production or further iteration.

The first physical prototype. This version is used to test functionality and identify major design issues.

Refinements have been made based on testing the first prototype. This version may include bug fixes, component changes or layout improvements.

The final version of the PCB, ready for production. It incorporates all lessons learned from previous iterations.

By incorporating design changes directly into the next iteration, we prevent:

• extra PCB orders
• unnecessary waiting time
• thanks to our cobots, we have no setup time

Iterating is therefore not only faster, but also more efficient.

By giving the different iterations their own colour, you can see at a glance that you are still in development.

But: colour is not a detail.

Deviating from the standard green solder mask colour is actually undesirable for (proto) series. Many AOI systems are optimised for green PCBs.

This is because:

• green provides the best contrast with copper, pads and silkscreen
• the reflection is more predictable
• detection algorithms have historically been tuned to this

Other colours can lead to lower detection accuracy.

Colour can be a simple iteration tool. But for reliable assembly, inspection and scaling up, green is often still the technically best option.

Iterate where you can. Standardise where you must.
