NON-PLATED HOLES | PRINTED CIRCUIT BOARDS | 10.1 This refers to plated through PCBs: If we do not have | PRINTED WIRING BOARDS PROTOTYPING | any information from you as to which holes are to be plated-through and which are not, we will determine this to the best of our | PRINTED WIRING BOARDS PROTOTYPING | knowledge. 10.2 If non-plated holes are positioned in a pad, this pad must be bigger than the hole by at least factor 1.5. Otherwise some | PRINTED WIRING BOARDS PROTOTYPING | or all of the pads may be removed. | 11. DATA PROVIDED (DATA INCONSISTENCY) | 11.1 If drilling and measurement plans are included that do | PRINTED WIRING BOARDS PROTOTYPING | not match the drilling program or the contour according to the gerber-data, then the drilling program and the gerber-data will be binding in all cases. | PRINTED WIRING BOARDS PROTOTYPING | | 12. PCB CONTOUR | 12.1 If not otherwise stipulated, the PCB contour will be determined by the centre (=centre vector) of the contour lines | PRINTED WIRING BOARDS PROTOTYPING | provided in the order data. If Slots are represented by you by rectangular outlines, then we assume generally that the corner radius is contained. | | PRINTED WIRING BOARDS PROTOTYPING | 13. TECHNICAL ...

The nearer the deadline draws to the compulsory implementation of lead-free regulations (ROHS), the greater the attempts to achieve lead-free solutions | PRINTED WIRING BOARDS PROTOTYPING | that are comparable to the “all-purpose answer” SnPb in terms of technology and cost. Two systems are particularly predominant: tin/silver/copper (SnAgCu) and, more recently, stabilised | PRINTED WIRING BOARDS PROTOTYPING | tin/copper (SnCuNi). Although the level of efficiency of both systems is not yet completely clear, the following presents the latest information: SnAgCu There is more | PRINTED WIRING BOARDS PROTOTYPING | experience in the field of silver systems. Here, differentiation is made between the Sn-3.5Ag-0.7Cu, Sn-4Ag-0.5Cu and Sn-3Ag- 0.5Cu systems which vary in use from continent | PRINTED WIRING BOARDS PROTOTYPING | to continent. However, the agreed expert opinion (IPC/Soldertech-Conference Brussels 2003) is that the technological differences between the three systems are negligible. Sn-3.5Ag- 0.7Cu is the | PRINTED WIRING BOARDS PROTOTYPING | most common alloy in Europe. SnCuNi Although there are even fewer field results for the stabilised ...
