1431. Glossar: Component Hole  
Component Hole Description:Component Holes are drills for wired components used with Through-Hole Technology. In doublesided or multilayer boards the holes will be plated through.   
1432. Glossar: Overproduction  
Overproduction Description:The production of printed circuit boards involves chemical processes that have a low risk of failure. We increase quantity for series production to yield ordered quantity a  
1433. Glossar: Hard Gold  
Hard Gold Description:Electroplated hard gold is an abrasion-proof surface used for gold fingers. We galvanically build nickel on the copper track. Then gold is plated over nickel.  
1434. Glossar: HDI  
HDI Description:High density circuits demand high accuracy from production. If you use SMD components and fine line (track <125µm, drill <=0,2mm), we speak of HDI PCBs. HDI stands for High Dens  
1435. Glossar: Hydraulic press  
Hydraulic press Description:Machine for laminating multilayer boards. During this process pressure and temperature must be precisely controlled.  
1436. Glossar: Sequential Build Up  
Sequential Build Up Description:Production of a multilayer printed circuit board in several lamination sequences. Especially multiple burried vias in high density boards (HDI) require the SBU technol  
1437. Glossar: Leakage current resistance  
Leakage current resistance By moisture or impurities between two points on the, in principle insulating, PCB base material, a measurable current flow is measurable if a correspondingly high voltage i  
1438. Glossar: CTI  
CTI CTI stands for Comparative Tracking Index. The CTI defines the leakage current resistance of printed circuit board base material.
