... Stellen durch einen Entwickler herauslösen lassen. Unterschieden werden Positivresiste oder Negativresiste, je nach Belichtungsart mit positiver oder negativer Leiterbahnstruktur auf dem Film. Entsprechend Dicke | CIRCUIT BOARDS FAB | und chemischen Verhalten unterscheidet man Galvano- oder Ätzresiste. | PINHOLE | A small imperfection that penetrates entirely through the conductor. Nadelloch Nadelstichartige Löcher in Leiterbahnen | CIRCUIT BOARDS FAB | durch Ätzfehler, Fehlbelichtungen oder im Lötstopplack. |PINK-RING | An area of bad adhesion around an innerlayer pad Pinkring oder Redring Rot-Ring Zone schlechter Haftung, auch | CIRCUIT BOARDS FAB | Rotring genannt, die durch das Eindringen von Säure in die haftvermittelnde Kupferoxidschicht der Innenlagen entsteht (meist über Bohrungen). | PADF | The portion of the | CIRCUIT BOARDS FAB | conductive pattern on printed circuits designed for the mounting or attachment of components.

... mount lands. If the air gap falls below the minimum, then the manufacturer will request a window void of the soldermask at that location. | CIRCUIT BOARDS FAB | (Also take into consideration that there will be some etch compensation enlargement prior to plot. This often times causes the CAM operator to shave the | CIRCUIT BOARDS FAB | sides of the surface mount lands to ensure that there will be no lifting and redepositing of soldermask flakes onto other features of the part.) | CIRCUIT BOARDS FAB | Open Road: The standard rule should permit the windowing and voiding of soldermask in the area. Otherwise, construct the land width small enough to permit | CIRCUIT BOARDS FAB | a 0.007" air gap. SOLDERMASK CLEARANCE Bottleneck: Many Gerber files for soldermask come with the clearance for the features as one-to-one. If the manufacturer left | CIRCUIT BOARDS FAB | this artwork as is, the result will be end product with soldermask on lands. This is not acceptable in most cases, though IPC standards permit | CIRCUIT BOARDS FAB | encroachment on one side of the feature (for surface mount). By providing the soldermask ...
