We have Heller, 1707EXL now. It has a removable support for the mesh conveyor that just pull out (clipped in). Had an Electrovert and they were bolted on and very tuff to change out. The oilers Im not sure I care for though,they have a metal rail t

I thought it might be the oven too, except it seems the splatter is too small for drips from the oven, secondly, when I ran a couple of bare boards among the populated boards we saw no splatter or flux contamination. So it seems it comes from the bo

I want to ask some advice from you guys how to clean out the water from PCB Dry Oven. The process is firstly wash the PCB and secondly put into the Oven to dry. After drying process,the water was dripping over the floor from the Oven Door and Body.

Just thought of something while on the beach. We made a paste change several years ago when we installed another surface mount line. At around that same time, our maint. crew changed chain oil and about 2 months later changed when they oiled the ch

I have seen there is flux like stuff dripping off from the exhaust area of the reflow oven onto the board That would be the issue of poor maintenance.

Are you doing PIN IN PASTE (intrusive reflow) ? If so, then paste can be dripping through the pcb holes and onto the oven bottom heaters / baffles . Or, if any of the SMT pads have vias in them, paste may drip through them if they are not sealed. Whe

Ken; my experience has been that eventually the flux builds up in the vents and then drips back down on the boards. For a simple oven with an air cooler the flux must go somewhere. Better in the ducts than in the oven. Just replace the ducts every ye

Hi smtspecialist (man I gotta get me a name soon), NO! Your oven cannot contaminate your process. Unless you have flux residues dripping on your board, there is nothing to worry about. Now having your operators switch from leaded to lead-free smo

I have been working on Pb-free assemblies of screw terminals (terminal blocks). Unlike, other pin-in-paste conducive components, these component has square headed leads. We have been facing issues with the solder dripping into the oven. We were able
