... Metal Price 12 – 13 € 7 – 8 € Leaching (CU peeling) Agressiv, high Leaching - Rate Leaching Rate 0,5 of SnAgCu Soldering | PRINTED CIRCUIT BOARDS PRODUCER | error rate compared with SnPB Equal solder bridging, more non- soldering Equal solder bridging, more non-soldering Costs must be kept in mind. The silver system | PRINTED CIRCUIT BOARDS PRODUCER | is approximately 40% more expensive than SnCuNi due to the use of precious metal; also, there is the ecological disavantage. Lead Sensitivity The problem of | PRINTED CIRCUIT BOARDS PRODUCER | lead sensitivity during the lead-free conversion phase in 2006 remains unsolved. Structural changes in lead-free soldering caused by remains of lead (even below 0.1% weight) | PRINTED CIRCUIT BOARDS PRODUCER | in processing containers have been observed. Structural coarseness occurs in SnAgCu if there are stressful temperature changes even well below 96 C? (degradation acceleration). Lead | PRINTED CIRCUIT BOARDS PRODUCER | secretion occurs in bordeline grains in SnCuNi systems which, under mechanical tension, can create weak spots. Splitting is possible when soldering heat cools. Conclusion There | PRINTED CIRCUIT BOARDS PRODUCER | is no doubt that the ...

... incoming data packages of varied quality, outdated CAM systems, and a shallow talent pool have many front-end engineering departments struggling with data package bottlenecks. | PRINTED CIRCUIT BOARDS PRODUCER | How can fabricators best resolve these bottlenecks and get onto the open road? For starters, front-end engineering must be sure the rest of the front-end | PRINTED CIRCUIT BOARDS PRODUCER | process is as efficient as possible. To that end, here are suggestions and checklists that can assist fabricators in the review of their own front-end | PRINTED CIRCUIT BOARDS PRODUCER | systems. DATA FORMAT: 274D VS. 274X Bottleneck: 274D Gerber is one of the oldest tools available, and many designers use this format as their sole | PRINTED CIRCUIT BOARDS PRODUCER | output option. With 274D data, the front-end operator is left to deal with many issues, some even prior to data import: * Locate the aperture | PRINTED CIRCUIT BOARDS PRODUCER | wheel within the files. * Is the wheel for one file only or for all files? * What is the format of the wheel (inch, | PRINTED CIRCUIT BOARDS PRODUCER | mm, hard or soft dimensions, trailing zeros omitted, etc.)? * What is the format of the Gerber files? * Are ...
