| | Dearest Jennifer, | | | | Ooooops! Forgot which one I was writing - please forgive me. Ah yes, SMT and you, you see even we don't get it right. If you combined all our answers, you would get close - as close as when we get frustrated. | | | | And on it goes, | | | | MoonMan | | Okay Earl - my favorite little MoonDoggy - here's my quandary: | | I *have* to come up with a market segmentation. Doesn't matter that it doesn't make any sense, doesn't matter that it doesn't apply to any particular manufacturer | | I understand the logic that the market is segmented by the end-user groups and what they need to place and how fast. So, since this irrelevant documentation *has* to be created from the manufacturer's point of view, is it best to segment by speed? For example, the "100-5000 cph" category would encompass bench-top, most multi-placers, and prototype machines. The emphasis in that previous statement being on "most." This categorization would go on arbitrarily to 100K+, I would assume. | | Will the IPC-9850 document "Surface Mount Equipment Performance Characterization" have any effect on how the market is lumped? My argument was to wait on this documentation until AFTER this has gone into effect / been accepted into the industry. | | Sorry to be a pain in the neck - I'm almost as confusing as the industry seems to be, but I really appreciate your (and everyone else's!) input in this murky little world. | | Jennifer | | Jennifer,
I do seriously empathize (is that even close to being spelled right? - I don't do it too often). We're all in the same quandry. This stuff changes daily, if not more often. However, in the meantime, I'd go with CPH for chip devices (yesterday's Fuji went 60 + million or more CPH - tomorrow it will go billions) and another rule for accuracy and repeatablility - even though they all have to be equal here with part sizes shrinking (part recognition and alignment plays another part here - you should factor that into the equation). One or more such suggestions aluded to this as K3, Scott, and others mentioned.
It's one thing to go faster than hell. It's another matter to place accurately fine pitch devices and everything in between. Thing is, it's all getting faster with lasers and improved optics.
Whoever said Fuji, Panasonic, and Sanyo goes fast wins - today. Whoever said MYDATA, Philips, Universal, Zevatech, Siemans places everyting well wins. Whoever said there's a cross over wins - today only. Philips went faster than anyone two or three years ago.
Sweet Jennifer, please forgive me at a time of total frustration, ignore the manufacturer's hype and go with what you'd do if starting a CM operation. Plot it out according to your customer's needs. This part of the conversation takes on new meaning as flexibility, dedicated production requirements, and even cell type manufacturing.
If you have high mix and low volume, you might go with MYDATA, Philips, Universal (name says it all), Siemens, and Zevatech. If you are going all out to hell with high volume (consistent), low mix go with Fuji, Panasonic, Sanyo, etc. I'm saying, again, it's all up to the person buying the equipment for a particular application - today only. Tomorrow, it will be different.
Maybe you should chart it all out in a spreadsheet then timeline for your presentation. This will work for today. Have I already said this?
Damn, I'm turning into a bitchy raving maniac over this. However, I care deeply for you. What was your name again?
