Mine doesn't either (we are prototyping using 0805 resistors since any smaller is a pain to debug/solder out/in)
Regarding the 4x array, it is fairly cheap (about 15 times a single
0805, in the 5% version about 3 times a 0805 resistor). So a quad respack compares to a 0805 if you can live with the 5% tolerance (we often can, since only a portion of a design needs precision resistors)But here is the point, since our placement costs are high, using a resistor array means ony one placement instead of 4 placements and thus the total price is much lower. We cannot use them however since the production cannot solder them reliable. We have used the standard layout from the manufactor and enhanced it further but they could not get the failure rate down :-( We can however handle 0402 parts reliably
Another really nice part is the dual BJT: BC847BPN - you should check it out (it's cheap also)
Good point. I have tried for the last year, but my suspicion is that the production guys simply is overbooked with work and also that they lack the experience and drive to improve the failure rates of special components. Its quite sad to try to optimize a design and being told the production cannot use the suggested parts.
I guess another solution would be to find an expert consultant, that can bring us further
We have a pretty high volume (more than 100mill SMD part mounted per year), but prefer to mount only SMD inhouse and take the labor-extensive work abroad
