Small volume batch conveyors

While negative pressure conveying systems have been covered in some detail in Chapter 4, there is a small sub-set that will be considered here. Small volume batch conveyors, or simply vacuum conveyors , generally consist of a small tank and a relatively short conveying line in which a vacuum is generated, and this is connected to a material feed hopper. Once the required negative pressure has been reached using the attached vacuum pump, a valve is opened on the feed hopper and the material is conveyed into the vacuum tank. The system...

Soldering of prototype/low-volume boards may be done by contact soldering of each component, by a manually guided hot-air tool, or in a small batch or conveyorized oven. Each step up in soldering sophistication is, of course, accompanied by a increase in the investment required.
