Hi Jon, well,i think that wirebond is still the best option at the moment since it is more flexible unless size is one of the important factor.

Let me make it simple than! one controller should be enough for a 400 sq ft room as a good rule of thumb. Although there are many factors that can affect this rule of thumb so read your graphs and take the approciate action. Dave

Hi, Ok, thanks for the info, and I had not considered that factor. Is this an issue related to the reflow temperature change in the oven, or a temperature change in normal product use issue? I will check out the standard, and do you know where it's

Does alloy 42 lead frame on a QFP100 make lack of coplanarity (let's say 2 mils), a critical factor to have non-wetted leads? Lead coating is tin lead 90/10. afm

That will depend on so many factors: solder type / flux type sphericity of balls in paste stencil type (laser chem etch, electro form etc.) print paramaters I will tell you that it can be done.

Use "40" as a down and dirty conversion factor, where: * Multipling X mm by 40 gets Y thou * Dividing Y thou by 40 gets X mm

We agree with John about his comments on the controlable factors relating to your printer, but we'd add that paste formulation and mesh are also contributors to nice looking bricks.

Depends on your specific application. Can you handle lower reflow temps? Can your parts handle higher reflow temps? What environment will your assembled product have to endure? Lot of different factors come in to play when choosing the right allo

Hi Everybody, Can enybody tell me what is acceptable level of defects for Wave soldering?I know that it's depends of many factors,but I want to benchmark my process. Thank you

Agreed. You will find different part manufacturers have different coplanarity specs. In fact I have on supplier that calls out 7 mil max coplanarity. Then factor in board bow and twist and it becomes a real joy.
