Viscom AG announces the release of vVision 2.4, successfully delivered since mid-2017 for its modern operating software. Among the most important optimizations are a time-saving inspection program creation – especially for new components and special component types – and comprehensive 3D advancements like the 3D solder joint inspection for chips.

We are placing a gold plated device (LCC) to a NiAu PCB using a SnPb No-clean solder. We're noticing quite a bit of difficulty with reliable joints (intermittent connectivity) and if we have to rework a particular device, adjacent devices of this sa

The solder alloy does not change based on the flux. Your potential for embrittlement is the same [providing the metal of the solders are the same] with either solder. We would guess the OA flux is [and drag tinning are] removing corrosion from the

The issue is surface tension around the connector. Your tip needs to have more surface tension than the pins of the connector as it forms a cluster when being soldered. When I used to solder superfine connectors with a metcal iron it had a horses hoa

According to seho, for multi dipping the process window is very small and they would prefer drag soldering which has a wider window. What is your view on dip vs drag? Why? Other machine user also share the same suggestion?

Drag the iron and molten solder over the thermocouple to the left, encapsulating the bead. Now, obviously if you are left-handed, reverse everything. This is a foolproof way to attach thermocouples. I used to have a lot more difficulty with them u

Hi, Sorry to drag this thread up again, but we were recommended to change the wave to SAC305, but is everyone recommending SN100C? That seems to be the feeling on this thread. What flux is used? Regards, Grant

We are having difficulty with bridging on a 2x50 pin 0.050" fine pitch connector using our selective soldering machine. It usually bridges at the end of the row, but sometimes it bridges all the pins together as it drags across (solid bridging). I

| I am a former employee of a drag soldering machine manufacturer. For years they attempted to devise a method of soldering surface mount devices via the drag soldering machine. Bridging was the largest problem along with component damage due to ex
