Solder Paste The solder paste mixes are improving as the demands of reflow soldering for SMT increase. Selection and specification of the optimum paste is a key item in the reflow solder process. B.

Reflow soldering is the most common process used by the manufacturers and repair shops to mount the electronic components on a PCB. Reflow is the stage of “reflowing solder” where the ‘ solder ’ or ‘ solder paste’ changes its state from Solid to Liquid, at high heat temperature to make a complete and proper solder joint on PCB With the ability to reflow solder, they embraced the use of SMDs and began to look for faster ways to use them. One obvious problem to be solved was the application of paste solder prior to placing components on the PCB; the answer was obvious: solder paste stencils.

Batch solder system. FRITSCH combines easy handling with low costs in the batch solder system. The user-friendly surface enables the individual programming to reduce setup-times to a mnimum. It doesn't matter wether prototyping or serial production: The batch systems are the perfect solution for daily work.

The reflow soldering technique resembles the traditional soldering process in many ways. But, the one major difference is that it uses heated air to melt the solder instead of a soldering iron. Reflow soldering is the most widely used method of attaching surface mount components to printed circuit boards (PCBs). The aim of the process is to form acceptable solder joints by first pre-heating the components/PCB/solder paste and then melting the solder without causing damage by overheating.

Process Description: Reflow During the reflow period the flux is activated, the flux cleans the surfaces and the solder is heated until it starts melting on all pads. This normally takes 3‐8 seconds, at Hotbar temperatures around 325°C (Hotbar touches the

The purpose of the reflow soldering process is to submit the circuit board and components to a uniform level of heat that will melt the solder paste without damaging any of the electronics. Reflow soldering typically includes four distinct stages, each of which involves a different level of heat. Reflow soldering is a very effective method for soldering circuit boards with lots of surface mount components.

A maximum ramp rate from ambient to peak of 1-1.5°C/second is recommended. If the solder paste is heated too quickly, Radius inspection at a solder station level indicates the changes of solder volume at a solder station, which is caused by solder paste printing technology or too much reflow solder. Radius inspection of solder balls demonstrates coplanarity from solder joint to solder joint or from board to board. However, Use of Nitrogen in Reflow soldering adds some cost but considering the long-term saving due to high quality and the sound solder joint with less repair/rework it can be managed and ultimately leads to the profitability of any organization.

I have some solder bridges on some HVQFN UARTs, (The same ones you use on the WiFly Shield) but I think I can fix that with the Hot Air. My issue with the HVQFN parts may be the solder mask layer, the kepton stencil already had some breaks between pads after I used it.
