| Hi, | | We are running 0402 component on the TCM1000 and we find that teher will be missalignment on 0402 Capositor. We have identified that the missalignment is caused by the wrong information from the vision system while doing vision centering.

5 Steps to Eliminate Bridges: 1. Establish (wave) Parallelism First and foremost, you must establish board-to-wave parallelism. This is the prerequisite to any wave solder process control. For an understanding of the power of this approach go to ht

your comments will be appreciated, please; IC tests have been performed on two kind of Raw PCBs (HASL) samples by adopting three different methods : First Sample (supllier A) - Omegameter 600 SMT, solvent=40�C: extratcing time 10 min result = 0.2

I have just started production run using this component. After reflow I see that there is an undercut of solder between the pcb and the lead instead of a fillet. This means that some of the leads are sitting above the solder with no wetting to the co

there is an IPC standard for machine accuracy and repeatability. Here it is how it works. You have to place certain number of parts on a specially designed PCB(that allows placing variety of parts on big part of the machine work area). After that you

The CDROM player in my personal computer just died and I replaced it with a more lively unit. Being an inveterate gearhead, of course I had to field strip the old CDROM player as soon as I pulled from my PC [and got the new one running]. There are

Can't find "WS601" on the Alpha site. What is that stuff? So, with nothing to go on, I'll just guess ... Yer probably cold welding the solder particles together. The nozzle size (inside diameter) determines the dot size. * With glue, small dot si

We use an Intermec 3240 Thermal transfer printer and print on polyimid label material that survives the reflow and wave solder (top side only) process without turning black. Labels run around 3-4 cents per depending on the size (We found Imtec label

WOW!!! How do people get these coo toys? Comments are: * IPC-7530 is not a specification. It is merely a guideline. [IPC-7530 �Guidelines for Temperature Profiling for Mass Soldering (Reflow and Wave)�] * What makes you say a 20-micron intermetall
