Hi mate, in humble opinion, Hot air Convection types are here to stay. Some machine designer folks are combining IR and Hot Air Relow into integrated technological units for commercial sale to folks like us. Dave F tells us that another group of d

The magnetic thing from the sot23 thread made me think of somthing from the past. Does anyone have any experience with vibrating boards during reflow? I know for a fact that if you vibrate a board during reflow it will alow the parts to "float" and

We are using a vapor phase oven which we have used successfully for a number of years with both leaded and unleaded solders. Recently we experienced problems with a no lead BGA that has low silver balls. The problem is that the soldered boards do no

What solder are you talking about and what reflow method are you using? High Melt Alloys: SN96 (Sn96/Ag4 or Sn96.5/Ag3.5) - Simliar to SAC305 although normally uses Rosin based flux that can required more extensive cleaning. Pb85 (Pb85/Sb10/Sn5) -

We used to use an APS Gold GF-120 before we went lead-free and the HT version came out. It worked fine for low volume and proto runs though not as much control over the profile as an oven with more zones. We actually had a batch oven from Bomir befor

Hello everyone, Talking to my boss today I was able to determine what we're really looking for in terms of reflow soldering. The company is not looking to do a volume run; we're trying to solder chips for prototype boards, which are currently done w

The Manncorp machines are Autotronik machines re-branded. These are Chinese built while pretending to be German, they are seemingly capable enough and do come in at very attractive price points. The FLX from Essemtec is in many ways a slicker machine

What type of flux is in your solder paste? Active or No-Clean? With lead free solder you really should be using an active flux. The lead free oxidizes during reflow if you are not using a Nitrogen or Vapor Phase reflow. So a more robust and activ

Hi chapeshiel, I had at my former workplace 2 pcs Rehm oven with vacuum system, and did not work properly. Loads of hours of downtime with servicing because the conveyor system is separated in the vacuum area from the main conveyor system, and the t

Hi, We used a batch oven from Reddish Electronics out of the UK. It was convection, and ok, but had limitations. Batch convection ovens start to heat up, so the metal of the oven is hotter and hotter and it effects the profile. So we ended up need
