DRILLING HOLES WITH HIGH LENGTH-TO-DIAMETER RATIOS
Draft:Deep Hole Drilling; Deep Hole Drilling
In the field of manufacturing technology, deep hole drilling refers to the drilling of bore holes with high length-to-diameter ratios.
Through-hole technology         
  • A box of [[drill bit]]s used for making holes in printed circuit boards. While tungsten-carbide bits are very hard, they eventually wear out or break. Making holes is a considerable part of the cost of a through-hole printed circuit board.
  • Axial- (top) and radial- (bottom) leaded [[electrolytic capacitor]]s
  • Components like [[integrated circuit]]s can have upwards of dozens of leads, or ''pins''
  • Through-hole devices mounted on the circuit board of a mid-1980s [[home computer]]. Axial-lead devices are at upper left, while blue radial-lead capacitors are at upper right
MOUNTING SCHEME USED FOR ELECTRONIC COMPONENTS THAT INVOLVES THE USE OF LEADS ON THE COMPONENTS THAT ARE INSERTED INTO HOLES DRILLED IN PRINTED CIRCUIT BOARDS AND SOLDERED TO PADS ON THE OPPOSITE SIDE MANUALLY OR BY AUTOMATED INSERTION MOUNT MACHINES
Through-hole; Thru-hole; Plated through hole; Plated-through hole; Plated through-hole; Axial-lead; Radial-lead; Non-plated through-hole; Non-plated through hole; NPTH; Non-Plated Through-Hole; Non Plated Through Hole; Plated Through-Hole; Plated Through Hole; Metallized through hole; Metallized through-hole; Metallized hole; Metallised through hole; Metallised through-hole; Metallised hole; Metalized through hole; Metalized through-hole; Metalized hole; Metalised through hole; Metalised through-hole; Metalised hole
Through-hole technology (also spelled "thru-hole"), refers to the mounting scheme used for electronic components that involves the use of leads on the components that are inserted into holes drilled in printed circuit boards (PCB) and soldered to pads on the opposite side either by manual assembly (hand placement) or by the use of automated insertion mount machines.

Drilling engineering

Drilling engineering is a subset of petroleum engineering.

Drilling engineers design and implement procedures to drill wells as safely and economically as possible. They work closely with the drilling contractor, service contractors, and compliance personnel, as well as with geologists and other technical specialists. The drilling engineer has the responsibility for ensuring that costs are minimized while getting information to evaluate the formations penetrated, protecting the health and safety of workers and other personnel, and protecting the environment.
