With PCBs being in such high demand, it’s important to be able to produce them as quickly and efficiently as possible to meet production goals and retain customers.
There are many factors that contribute to efficiency and speed in the production process, such as parts reject rate, time to complete key processes, and time spent handling parts between processes.
One way to increase efficiency is to use a custom-made PC board basket to hold your printed circuit boards through your parts finishing processes.
You might be wondering how a basket for printed circuit boards can increase production efficiency. While the specifics might vary depending on your particular production process, there are a few ways that a custom printed circuit board basket can drive efficiency and increase productivity:
In one parts washing process, a printed circuit board manufacturer was using an older set of baskets that were falling apart and rusting through. Although scratches weren’t generally a major worry, severe damage to boards from rusted metal poking through a printed circuit was enough to ruin the board’s functionality.
Additionally, rust flakes from the degraded baskets would contaminate the boards and circuitry. This contamination could further compromise the boards, leading to higher parts rejection rates and reduced production throughput.
Finally, the degradation of the baskets kept their lids from shutting properly—the manufacturer had to use alternative mechanisms like zip ties and bungee cords to keep the lids secure. There were two major problems with this:
The manufacturer needed a new set of baskets, ones that would be easier to handle, and would not rust up when repeatedly exposed to water-based wash processes.
This is where design and construction of a custom circuit board basket come into play.
To this end, a basket made with a stainless steel alloy, such as grade 304 SS, would be ideal for a water-based wash process. This alloy of stainless steel would resist rust caused by plain water exposure, preventing future contamination of parts. Additionally, this material would be more than strong enough to carry lightweight circuit boards through the wash cycle.
Keeping the open space of the wires as wide as possible would allow for greater air flow, enabling circuit boards to dry faster after washing. However, the spacing between wires can’t be too large, or else smaller circuit boards with widths of less than 2” could fall out.
Once the basic design is complete, it should be tested against the manufacturer’s process and environment using virtual physics simulation software to ensure that any potential causes of failure could be eliminated beforehand. If the basket fails the test, the software generates a report on the cause of the failure so that the design can be corrected.
After the design passes muster, the basket can be manufactured. Here, using automated manufacturing equipment helps to ensure consistent quality, even in unusually-shaped custom baskets.
