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

Hi, Thanks guys for all the suggestions. I am going to check what options we have for top side heating. Do people recommend we get convection for that? Also, we seem limited to 60% in the machine setup, and does anyone know how to run the top lam

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

We've had much trouble with flex circuits. As previously mentioned, you must have local fids for the board or the BGA itself (if panelized). Other troubles we experience are drilled holes for pinned connectors. Unless the PCB manufactur has some w

We currently have RMA and WS soldering processes here and do batch cleaning for both. We are experiencing some capacity issues and are interested in looking at an IN-LINE aqueous wash. My experience with in-line wash is only with WS. 1. Since RMAs

We currently are building a pcb that has gold fingers, about 36 in a concave V overall shape from .275 on the outside edge fingers tapering down to .197 in the middle of the 2 inch span that plugs into a shelf connector. These fingers are on both sid

I read the request months ago with great interest. However, a request is hardly an exemption. Here's my issue with the language: "23. Lead in finishes of fine pitch components other than connectors with a pitch of 0.65 mm or less with NiFe lead fra

There are a couple of things that you can do. First thing to do is take a flashlight and shine it in the card edge connector of slot 2 and see if a passive component or any other part worked its way into that slot. This will cause multiple leads in

I am having some problems with some of my pcbs at ive solder. We are using an ersa versaflow. It has an automated spot/spray fluxer (Interflux Pacific 2009M) , 1 preheat stage, a leaded pot/nozzel, and finally a lead-free pot/nozzel. Nozzels move, b

Hi jepoy + a very frazzled man thanks for your suggestions,here is how it went:- I found a couple of these VM1710 boards and tried one and still nothing. I really wanted to see if power was getting to the camera and anything coming out. I was loo
