that production accuracy precision needs to increase with it. Even small alignment errors during manufacturing will render the board useless… especially when it comes to systems that require multiple mating cycles. By reducing the total number of connectors on a board, we reduce the risk of misalignment of a single connector pair. But newer connector designs are also seeking to solve this issue. For example, floating connector ranges – such as Harwin’s Flecto – build in additional tolerance while also combining power and signal connectors on a single unit. Specifications will vary between vendors, but for the Flecto, these fine-pitch, high-pin-count board-to-board connectors are able to withstand up to ±0.5mm misalignment in both the X and Y axes to give greater alignment tolerance alongside high-speed data transmission, mixed signal and power options.
Conclusion
The pressures on industrial and embedded systems have changed rapidly in recent years and designers are trying to balance a huge array of considerations to keep costs low, performance and durability while

also coping with the increased (and ever increasing) data volumes that come with IIoT connected systems.
However, there is one fi nal element that, while not necessarily a change in the way these systems operate, is just as vital to consider: supply chain reliability. The use of dual sourcing for components can play a key role in futureproofi ng a design, but recent years have seen a rise in counterfeit and low-quality parts being misleadingly
sold, as well as websites listing products and “taking orders” for stock they don’t have… and never will. Supplier trustability is therefore vital.
As we began with, industrial customers are under exceptionally tight cost pressures and any design cost saving will be nullifi ed by falling victim to a scam. It is therefore essential that steps be put in place to verify the relationships between the component manufacturers and the distribution partners.
If a supplier uses a franchised distribution model, they should have put steps in place to prevent fraudulent or counterfeit parts and let you validate the relationship. Harwin, for example, lists its distribution partners on the website:
https://www.harwin.com/distributors as well as on
TrustedParts.com and any company that claims to be a partner that isn’t on these lists should be avoided.

E-tec design and manufacture a wide range of high quality socket bases for CCD-CMOS SENSORS.
Various socket terminations including through hole, smt and solder ball allow E-tec to offer a socket with any mounting option.
As with our test sockets, footprints are created to match the sensor in any pitch e.g 0.5mm, 0.65mm, 1.00mm 1.27mm, 2.00mm, 2.54mm, 3.00mm etc.. custom patterns are created with- out additional fees.
Over 25 types of socket contacts are available to match different sensor tail dimensions.
