Printed Circuit Boards Suppliers OSP = Organic Surface Protection for PCB or Printed Circuit Boards

... The electrodeposition of an adherent metal coating on a conductive object for protection, decoration, or other purposes. The object to be plated is placed | PRINTED CIRCUIT BOARDS SUPPLIERS | in an electrolyte and connected to one terminal of a DC voltage source. The metal to be deposited is similarly immersed and connected to the | PRINTED CIRCUIT BOARDS SUPPLIERS | other terminals. Ions of the metal provide transfer to metal as they make up the current flow between electrodes. | EPOXY SMEAR | Epoxy resin | PRINTED CIRCUIT BOARDS SUPPLIERS | which has been deposited onto the edges of the conductive pattern during drilling. Also called Resin Smear. | ETCH FACTOR | The ratio of the | PRINTED CIRCUIT BOARDS SUPPLIERS | depth of etch (conductor thickness) to the amount of lateral etch (undercut). | ETCHBACK | The controlled removal of all components of base material by | PRINTED CIRCUIT BOARDS SUPPLIERS | a chemical process on the sidewalls of plated through holes in order to expose | ETCHING | The process of removing unwanted metallic substance (bonded | PRINTED CIRCUIT BOARDS SUPPLIERS | to base) via chemical or chemical and electrolytic means. | ETCHING RESISTS | Materials deposited on the surface ...

... separate a layer of material from its base. This may be measured as peel strength, in pounds per inch of width, or as pull | PRINTED CIRCUIT BOARDS SUPPLIERS | strength, in pounds per square inch (when a perpendicular pull is applied to the surface of the material). Frequently used to refer to wire bonds. | PRINTED CIRCUIT BOARDS SUPPLIERS | | BREAKAWAY PANELS | Hardboards held together in a grouping with breakaway tabs. The panels make handling easier for automatic insertion and wave soldering. The | PRINTED CIRCUIT BOARDS SUPPLIERS | boards can be separated by snapping apart. | BREAKDOWN VOLTAGE | The voltage at which an insulator or dielectric ruptures, or at which ionization and | PRINTED CIRCUIT BOARDS SUPPLIERS | conduction take place in a gas or vapor. | BRIDGING ELECTRICAL | The formation of a conductive path between conductors. | B-STAGE | The condition | PRINTED CIRCUIT BOARDS SUPPLIERS | of a resin polymer when it is more viscous, with higher molecular weight, and insoluble but plastic and fusible. Semi-cured. | B-STAGE MATERIAL | Sheet | PRINTED CIRCUIT BOARDS SUPPLIERS | material impregnated with a resin cured to an intermediate stage. Prepreg is the preferred term. | B-STAGE RESIN | A ...

... in the departments themselves who are responsible for the regulation of a smooth flow of production. From the first production step, the respective operators | PRINTED CIRCUIT BOARDS SUPPLIERS | promise to complete all RMP orders by a certain date. In this way the operator responsible for the subsequent step can have all of his | PRINTED CIRCUIT BOARDS SUPPLIERS | technical and organisational equipment fully prepared to receive the handover of the order. If he knows the time point, he is also obliged to | | PRINTED CIRCUIT BOARDS SUPPLIERS | "PROMISE“ | the time of completion by his department so that the following operator can be prepared, and so on. By means of a PPS | PRINTED CIRCUIT BOARDS SUPPLIERS | support system expressly developed for this purpose, communication between operators has been simplified to the extent that organisational work is minimal. In addition to the | PRINTED CIRCUIT BOARDS SUPPLIERS | organisation, of planning, production was examined to identify time- intensive procedures and ways of improving operational times by means of new machine technology or innovative | PRINTED CIRCUIT BOARDS SUPPLIERS | approaches to old manufacturing concepts. Our goal however, is one ...
