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

... educate the sales team about facility capabilities. The planner must know the manufacturing facility and its capabilities. By giving the process engineering department an | MULTILAYER BOARDS FAB | opportunity to evaluate the process traveler and artwork, the planner will not only have a better understanding of the process, but the process engineering department | MULTILAYER BOARDS FAB | will have the opportunity to make changes prior to the release of the product to production. Items to consider before the process traveler is generated: | MULTILAYER BOARDS FAB | * Material availability. * Shrinkage compensation. * Drill registration tolerance. * Drill size availability. * Etching compensations. * Plating compensations. * Routing compensations. * Testing | MULTILAYER BOARDS FAB | capabilities. * Time studies (provided by process engineering). * Daily capacity of the plant (provided by production control). LAMINATE MATERIAL PERFORMANCE Many manufacturing facilities have | MULTILAYER BOARDS FAB | multiple laminate vendors, which in turn have materials with different characteristics. For example, the internal ...

... orientation marks within the boundary of board. These marks could be the board reference so long as it cannot be read from the other | MULTILAYER BOARDS FAB | side. (This is for your protection to prevent the boards made inside out). | IMAGES | should comply with design rules that will result in | MULTILAYER BOARDS FAB | a board that will meet performance and cost requirements. - | SCALE MUST BE GIVEN, | tapes securely stuck to the backing sheet, track to | MULTILAYER BOARDS FAB | pad & track to track joints complete and the backing sheet clean. - Scale must be given and be at least 2:1. Plots must also | MULTILAYER BOARDS FAB | offer sharp edge definition and traces dense enough for blocking light when photographing. - Preferred on 7mil (178mm) thick base for stability. Films should be | MULTILAYER BOARDS FAB | plotted on laser photoplotter or on vector photoplotter using a minimum resolution of ½mil (13mm). - Preferred in Gerber® format although accepted in other formats. | MULTILAYER BOARDS FAB | (Refer to CID- 014 for information on Documentation in Digital Form). - files are the only acceptable form of supplying images for ...
