Peter, The Siemens placement equipment has a simple coding structure: HS50 - 50,000 CPH S20 - 20,000 CPH S23 - 23,000 CPH S27 - 27,000 CPH Well... you get the idea. I have no idea about the speed of the 'F' machines. We get around 70-80% of this

Well, to be honest, we have not had any problems with this. We tested several old frames we had inhouse, and put them in our washers for 50 cycles, and they did not get any fluid in the frames. We simply attach the labels with sheet metal screws in

In obtaining almost zero defect in solder wave. I would like to suggest the following: First,We must consider changing machine if it is more than 5 years old. second, use the right tools for the right job. Most of the traditional engineers will us

Agree with MKE, some reconditioned CP6 machines would be fine for you if you want bombproof equipment and low operation cost, but no flexibilty at all, unless you have small assys with few part numbers, If you want more felxibility, GSMs are OK, easy

Your problem is easy. Lead free solder is like 63/37 solder paste when it was started. We make things complicated. We believed before that lead free has high melting temp and will not produce good fellet so on.... The only thing you must do is to lo

All right all you Mydata techies. Here's the scoop. My old TP9 seems to be damaging (bending) it's A12 and A13 tools way too frequently. Like 4 tools in the last month. It appears the tool is colliding with somthing. My perfect operators SWEAR there

As per the title. I'm a manufacturing engineer writing from Italy. We have an old oven ETS/Universal branded that needs to replace a control card. It's an IR lamp oven still utilized to cure glue. Unluckily here there's no more availability of the

99% (there will always be that one that gets jacked somehow). Your old placement equipmment may affect this by dropped parts that get underneath the BGA, etc.. hopefully the placement accuracy will at least get the parts halfway on pad and they will

The use of nitrogen in lead free wave solder operations is primarily used to reduce or even eliminate drossing of the solder, thus improving solder yield. The higher priced lead free solder makeup (Cu, Ag) make this a more economical proces than the

We grease acording to PM schedule. The cable is very old about 5 years. We run 2 shifts. The transducer program and burnin test show the varance that we are seeing phisically so I can rule out the transducer. The motor may be the cause as it is of 19
