... work is completed, step into the fabrication analysis arena, where the game is one of checks and balances. You've got your design rules; fabricators | CIRCUIT BOARDS PRODUCER | have theirs. Checks and balances can resolve any conflicts between the two. Take soldermask layers, for instance. Often, these layers are not "intelligent" layers within | CIRCUIT BOARDS PRODUCER | a CAD tool; that is, there is not much in the way of capability checking within the tool. As a result, these are among the | CIRCUIT BOARDS PRODUCER | more troublesome layers for fabricators. The solution here is a fabrication analysis tool that can handle such issues as clearances, coverage, webbing, and so forth. | CIRCUIT BOARDS PRODUCER | For instance, most fab shops want the largest possible clearances in a solder layer so that mask doesn't end up on pads. On the flip | CIRCUIT BOARDS PRODUCER | side, copper is not supposed to be exposed. The two requirements - no mask on pads and unwanted exposed copper - must be balanced. It | CIRCUIT BOARDS PRODUCER | is not easy to do. How can the designer help? Devise a standardized clearance, or set the clearances at 1:1, and let ...

... of UL more than 100 years ago stood questions in the range of fire-protection-mechanisms in the foreground. Today all possible products, materials, constructions and | CIRCUIT BOARDS PRODUCER | systems are tested and evaluated regarding their electrical danger as well as their danger of accident and fire. And in addition there were examined alarm | CIRCUIT BOARDS PRODUCER | systems and the ability to discover, control and prevent fire. UL develops safety regulations, which are taken over frequently as ANSI standards. Underwriters Laboratories certify | CIRCUIT BOARDS PRODUCER | and register customers according to ISO 9000. What means this indication for the Microcirtec GmbH and their customers? Products with this indication have international a | CIRCUIT BOARDS PRODUCER | higher acceptance. Many customers wish or demand a UL marking. The marking offers easements in questions of the product liability and brings a higher acknowledgment | CIRCUIT BOARDS PRODUCER | at authorities. In order to guarantee the adherence to the examined values, a Follow UP service is furnished. An expert from UL visits regularly our ...
