OR: Stands for organic (organic acid based flux) with the absence of rosin and/or resin. If you want to know everything about the classification of fluxes get the J-STD-004 �Requirements for Soldering Fluxes� at following link: http://webvision.ipc

Hi John, I sent you a reply yesterday. I'm not sure if you got it. I'm new here. I clicked your name to email you. I assume that was the way you wanted me to reply, but I guess it wasn't :-). Anyhow ... I'm very interested on the step by step instru

There is no standard. Companies select a lower control limit based on the desired cleanliness. Guidelines to consider are: * With fresh resin beds, expect get 17.5 mohm-cm water into the final rinse and then it decreases from there. * Semiconducto

From my past experience, you can usually get away with OUT the chip wave if your SMD's are no smaller that 0805, and more importantly, there are no SOT23's. A nice, clean, inerted laminar wave (with a little smart or omega help) will solder your S

I currently have issues with "slivers" of solder on or behind QFP devices. This has only occured on PB Free boards (we currently produce PB and PB Free on same equipment). This is not tin slivers, this is a long thin sliver of solder measuring up to

I have the entire computer box assembly from a 1306/40 series machine. This was one of the first with the AC servo motors and digital drives. It was taken from a working CSM66 at the same time as I bought a CSM84. It was included to be used as spa

The CSM84 I have is 63" (1600 mm) wide, 57" (1450 mm) deep, and 54" (1372 mm) high, without the turret. The CSM84 is rated at something like 1600 Lbs (728 kg). I had to cut a hole and install double doors to get mine in. I can't imagine "carrying" t

Sami, Have you tried anything to reduce your print time. For example, use the fewest fiducials possible (2 in most cases) for alignment. Get rid of unnecessary inspection sites. Adjust the start/stop of your stroke to reduce wasted movement of th

Hi folks. If the solder is on the BGA but is not soldered at all on the pads, then you can discard BGA solder issues, by the other hand; you might be experiencing wicking due to heat is being absorbed on component so the balls on BGA are hotter than

We run a TP9 machine and had a very similar problem with it. On a TP9 machine there is a power supply board where all the voltages are generated. It is located on the bottom side of the unit. The problen was with one of the fuse holders. The co
