Hello Does anybody know any standard about SMD nomenclature? I mean any document saying about package type, shape definition saying that 0402 its exaclty .... Because I found some kind of documents at Top Line site, maybe u can share at forum with

Hi, They are a nice machine, and very low cost. We had one, and it was not fast, but it did a nice job. It only places one component at a time, however it was accurate on the 0805 components we used on it at the time. However I don't know how it wou

Hi, We are in the market for some Inspection Equipment. We have never bought any before but have trialed two types so far. A Mantis system, and a camera system with built in microscope. We are keen on getting the camera with scope so that we can use

We are starting to see issues with using Kester WS R562 with lead free components. The joints look grainy on almost all of the 0402'2 and other small components. Some of the solder does not solder to the terminations. These are hybrid boards which

Hi Folks, I hope someone can help me, Is the homeplate stencil design (for reduced solder paste) the same for preventing solder balls as it is for reducing tombstones? i.e. the reduction of solder paste under the component termination. I'm trying to

Zoinks!! Doing the homeplate design on 0402 will actually make your tombstones WORSE! Think about it. Your wetting forces are now on the ENDS of the device with no solder paste toward the middle of the device to tack the part down - a gauranteed f

Do all 0201's reject at the same rate? If even 1 P/N has a lower reject rate this can point towards a feeder problem. I have had a similar problem on a CP-IV-2 with 0402's that was caused by feeders. If all reject at the same rate it can be the PD o

Have you created block offsets for each board in the panel? We have rotated baords in panels but have not had to use block fiducials, we just use board fids. We place 0402s and 16mil fine pitch on multiple boards in a panel with boards rotated 180

Daniel, We'd recommend MyData's as good low foot print, short quantity machines. They have a good level of flexibility for the price and operation. Considering what you've described, an older used TP9 would suit you. I'll caution you, though, tha

We are running an upgraded, refurbished MyData TP9 machine in our high mix, low volume production. With those improvements it does okay on the 0402s. The TP platform is no longer in production but they are still providing good support for machines
