Hi, I have used both MYDATA TP9, MY9 and more recently MY12. MYDATA machines are just not accurate, and we did everything possible, and every kind of upgrade they had. We ended up putting in Fuji XP based machines, and the differences are very notic

Shameless? In APE's experience not so - air velocity/power is extremely important in carrying energy to the board and close loop control of that energy is crytical in maintaining a controlled environment - if a machine design requires that air is for

Thomas, The first thing I would suggest you to do is identify the type of problem your dealing with �pinhole� or �blowhole� before you can take the appropriate action to correct the problem. A pinhole is a void or cavity caused by non-wettable part

I would also like to add some more features of Assembleon XII platform. You had mentined that you already have GSM machine whose feeders could be used if you buy a new GSM machine. Assembleon XII machines such as Opal XII, can use GSM feeders as we

This is highly dependent upon your board, vision inspection, part rotation, part type, layout, number of P/Ns per (1 pers or 100 pers) feeder layout, optimization, nozzle changes, etc... all have significant impact on placement speed. I find if you

Frank, We are currently running lead free for approximately 1 yr. now but no where near the volumes you have mentioned. We are about 5k units per month. I personally am in agreement with you as far as OSP. I also do not like white tin finish since

We're not sure what you mean by temperature sensitive components. From an assembly process stand-point, every component we use is temperature sensitive to one level or another. More specifically, some of our products use polyphenylene sulfide (PPS)

This has always been a big debate on what is better. Few things to consider before getting into number of zones. What is the throughput and cooling requirements? Throughput is a direct relation to length of heating zone. Longer heating length

If I remember correctly since I cannot find my copy of IPC 600, I believe that the 20% reduction applies to "defects" and not the total etch process. By the way what is being used to measure down to .0005"? For this measurement to be correct it wou
