Rick, you have not heard everything, I believe Fuji is rating thier machines by cubic footage. I guess thats to keep the competition from making 9 foot tall placement machines. Gee, didnt someone try that with ovens a while back? I would still love

... and even if you don't trust the numbers in the brochures and specs: ask them to do the test in your presence or get a third party to come in and verify the claimed IPC9850 ratings, e.g. Cetaq. 26k is indeed a bit steep, and that's without the los

Can I please get some opinions on the best way to kit/present parts to the SMT line for high mix/low volume board manufacturing? We currently kit builds using a scrap rate assigned to different package sizes. It is O.K. but could use some refinemen

I don't believe that the TRS14's are suitible for lead free - the max temp rating from the data sheet is 275oC. When you get near temperatures like 350 C I'm under the impression that the oven itself would start suffering embrittlement damage. Howev

I appreciate your comments regarding the programmability of the Mirtec. What type of SMT machine do you use? How easy have you found it to transfer the SMT profiles to the Mirtec? How do you rate the Mirtec in handling top/bottom, multi-panel asse

I just received a reel of RoHS parts but I have a rejection rate of 15% since I started using it.Does anyone has experience this so far? My machine Mydata My12 with TPsys 2.2.5e

Hi Lawrence, I would agree with that in the main, however in some cases some machines can be almost "timeless". We don't go below 0402 (1005), missplacements are negligable, and a actual placement rate typically hitting 28-30K an hour makes "upgrad

Surely not? I thought it was all free & we were heathens (at least I'm guessing that's what the cable guy insult was meant to mean)for not welcoming it with open arms. O well, back to my biggest technical problem of the next two weeks - what SPF r

Hi, Yes, I would be interested to know what the nature of the high failure rate is with using lead free BGA parts with a lead process. I had been to a seminar where they said it was ok, but not ok to use a lead BGA in a lead free process. Regards,

Samir brings up a good point with convection ovens. The flow rate of the fans can move parts, which can cause tombstoning to very light/small components. Also, check you conveyor and or chain. If it is not running smoothly, even a slight shake o
