Hello all, we use a reflow oven from Rehm in our SMT production. At the moment we solder under nitrogen atmosphere (approx. 500ppm). Now we want to reduce the nitrogen consumption (costs etc.). What consequences can occur here? Especially on the s

Nitrogen is helping voids, so if you have specific parts that are prone to voids, you might start seeing more voids. Joints will probably look a little dull in comparison and this might affect your existing AOI programs.

While experienced inspectors may be able to determine the aesthetic differences between a lead-free PCB assembly and a tin-lead version, one cannot rely on the "experienced eye". "Less wetting out to the pad edges" (Figure A) and "graininess and lack of shininess of the solder joint" (Figure B) are typical comments about some lead-free solder joints. However, in cases where a Nitrogen atmosphere was present during the reflow of the solder joint (Figure C), there will be little visual differences between the lead free alloys and their tin-lead counterparts.

In PCB circuit assemblies the trend is moving to more SMD components with finer pitch connections. The majority of the assemblies still have a small amount of through hole (THT) components. Some of them can't withstand high reflow temperatures, while others are there because of their mechanical robustness. In automotive applications these THT components are also present. Many products for cars, including steering units, radio and navigation, and air compressors also use THT technology to connect board-to-board, PCB's to metal shields or housings out of plastic or even aluminium. This is not a simple 2D plain soldering technology, as it requires handling, efficient thermal heating and handling of heavy (up to 10 kg) parts. Soldering technology becomes more 3D where connections have to be made on different levels. For this technology robots using solder wire fail because of the spattering of the flux in the wires and the long cycle time. In wave soldering using pallets the wave height is limited and pin in paste reflow is only a 2D application with space limitations.
This elevator format oven utilizes vertical space to accomodate curing applications of up to 4 hours while only occupying 96" (2.5m) of floorspace. Perfect for underfill and encapsulant.
