Hi, We have spent the day trying to profile our Vitroncis Soltec Delta C wave with the new SN100C solder, but having problems with the heavy pins on some BNC connectors we are using. We have Interflux no residue flux, and we are using palettes, whi

It sounds as if the boards are designed in-house. Is this correct? If so, look for SMT versions of the BNC connector. I hhave used one from Johnson Components (http://www.johnsoncomponents.com) or look through http://coaxicom.com for something yo

Hi. I agree that the Soltec has weak, low-wattage preheaters, and also, the Soltec's fluxer is flippin' weak too. It doesn't do a good jab of atomizing the flux and getting good, huh-huh, penetration on the holes. I cranked up my Soltec's pressu

Hi Grant, You already have a few good answers. If you have but one to a few BNC connectors I would kind of use the advice here or do what you already are doing aka hand soldering. I would not install a Wave Solder line for a really low volume of BN

Is it possible the solder hole(s) is too large and the solder is falling back in the hole? I see this on right angle BNC type connectors. Is this happening on all component types? All areas of the boards? Always the same pins (but other pins in t

Hi, Thanks for the tip, and I will check that out! We have some heavy BNC type connectors, so they need a bit of heat, and this could be right that we are then overheating the flux. Regards, Grant Blackmagic Design

Hi, That's good news, and we did outs with SN100C as well on Wed, however we are still working hard on getting a good profile. We have some large BNC connectors, and they are hard to profile. We also have wave palettes, and these might be too thick

There is standard pick and place equipment such as the Assembl�on (formerly Philips EMT) ACM Micro and AQ-1 that can easily handle your snap-fit through-hole BNC connectors, in addition to other surface mount components and through-hole odd form part

Hi, We have a SMT production like, however we have very little experience with through hole assembly. We design everything to be completly SMT based, however connectors are the only part of our product that still requires through hole assembly. Cur

Hi Grant, You definitely have a pre-heat problem and not a flux problem. Pallets together with the BNC connectors put a large thermal demand on your pre-heating. 3 zones would be a good investment even with leaded solder due to the high thermal dema
