8 Simple & Technology Driven PCB Quality Control Methods
Feb 02, 2017 · Two effective quality standards are defects per unit (DPU), which measures the number of defects on each board, and defects per million opportunities (DPMO), a normalizing factor that measures the total number of defects on a million boards of different complexities. With these two metrics, manufacturers can track both product and process quality.

calibration of concrete batching plant
Concrete plant batching controllers usually control the "open time" of the gate in steps of 1/10 to 1/100 second. Since it takes 1/10 to 2/10 second to start the gate moving and it can be full open in 3/10 second a setting of 2/10 may drop no material while a setting of 3/10 can drop 50lb/20kg. Get Price.

Concrete batching is generally conducted at plants located at various strategic positions around a city or town to minimize transport time. Raw materials are mixed in elevated bins and placed directly into concrete trucks for final transport. This process is primarily powered by electricity, with small amounts of other fuels used on each site by small excavators used to move raw materials, etc.
