Making electronic prototypes [recommendation]

This are the first proto pcbs for a mini RF transmiter. The size was relevant. I decided to use smd components. No space wasted. The designer was inexperienced and the initial proto was a failure. Was not possible to mount components. The designer must be really involved in the building process, speaking fluently with the producer company. Any communication error could cause final failure.

At first stages, you must order little quantities to minimize losses. You can order 3-5 units to test solder, enclosing, etc. In the initial steps you must know you are going to spend some money. In order to save it sometimes it's a good idea to order proto pcbs with components soldered. This way you can test them inmediately once you receive it.

When your are designing a prototype, move slow. If you move quickly sometimes you will find some problems. For example if you are going to put your proto PCB on an enclosure, it's a good idea to choose a box somewhere close to you, buy one unit and then try to fit the pcb on it.

Always work with real models. Order some units of your proto pcbs to phisically test and mount in the real box. Sometimes you will use the first box, sometimes not. When you see it mounted perhaps you will get a new idea about it. Let your mind explore, touch and imagine playing with real models.
