... GOLD PCBS APPLICATION AREAS Immersion nickel gold process has long been an established surface refining process among printed circuit board techniques. However, in spite | PCB SERVICES | of many advantages over conventional solder levelling it has only been adopted for certain application areas. Nickel gold is utilized in particular where PCB surfaces | PCB SERVICES | are exposed to aggressive environments, for instance in mobile phones, or automobile electronics. Due to the consistent chemical precipitation of metal, gold is the obvious | PCB SERVICES | choice for all fine-pitch assemblings with under 0,5 mm grid spaces. Due to its smooth excellence, the immersion nickel gold surface is a better alternative | PCB SERVICES | to HAL, particularly for narrow SMD grids on both side of PCB`s. The actual wiring of a component is effected by means of a 4-6 | PCB SERVICES | my thick layer of nickel, and not by means of the extremely fine 0,05 to 0,2 my layer of gold which merely serves as an | PCB SERVICES | oxidation and diffusion blockage in order to extend the soldering conditions. ...

... held together in a grouping with breakaway tabs. The panels make handling easier for automatic insertion and wave soldering. The boards can be separated | PCB SERVICES | by snapping apart. | BREAKDOWN VOLTAGE | The voltage at which an insulator or dielectric ruptures, or at which ionization and conduction take place in | PCB SERVICES | a gas or vapor. | BRIDGING ELECTRICAL | The formation of a conductive path between conductors. | B-STAGE | The condition of a resin polymer | PCB SERVICES | when it is more viscous, with higher molecular weight, and insoluble but plastic and fusible. Semi-cured. | B-STAGE MATERIAL | Sheet material impregnated with a | PCB SERVICES | resin cured to an intermediate stage. Prepreg is the preferred term. | B-STAGE RESIN | A resin in an intermediate state of cure. The cure | PCB SERVICES | is normally completed during the laminating cycle. | BURIED CAPACITANCE | A method and technology for adding de- coupling capacitance to the innerlayers of a | PCB SERVICES | multilayer, thereby saving space and increasing functionality. | BURIED VIA | Connects one ...

... at the place of action. This is exactly the principle that we have adopted in our production. Although logistics and distribution still determine when | PCB SERVICES | an order must be completed, it is the operators in the departments themselves who are responsible for the regulation of a smooth flow of production. | PCB SERVICES | From the first production step, the respective operators promise to complete all RMP orders by a certain date. In this way the operator responsible for | PCB SERVICES | the subsequent step can have all of his technical and organisational equipment fully prepared to receive the handover of the order. If he knows the | PCB SERVICES | time point, he is also obliged to | "PROMISE“ | the time of completion by his department so that the following operator can be prepared, | PCB SERVICES | and so on. By means of a PPS support system expressly developed for this purpose, communication between operators has been simplified to the extent that | PCB SERVICES | organisational work is minimal. In addition to the organisation, of planning, production was ...
