Electronic – Designing electronics systems with weight constraints

pcb-assemblypcb-design

How would you go about designing a PCB with weight constraints? Suppose, the PCB has a weight constraint that say it must weight less than 140grams.

In searching for parts and components, I realized most if not all components' datasheets do not have any weight information. For example, I need to use two DB25 connectors among a few other connectors on board. None of them carry weight info in their datasheets. Similarly, ICs, discretes etc do not have weight information.

Do I just need to sample components and actually weigh them?

The short version is that most manufacturers don't provide weight data because it's rarely needed in most designs. So, yes, you'll most likely have to sample all the relevant parts. If you are building a device for volume, you can usually get free samples from the manufacturers (or their reps) - so you won't have to shell out money for parts that might or might not work.
