Understanding Reflow Soldering Oven and How it Works

A solder reflow oven is actually a useful piece of equipment for boards that comes with large quality of surface mount components or in making batches of the surface mount boards.

Reflow soldering in fact can help to assemble quickly high-density PCBs which could cause manual hand soldering challenges for even the experienced engineers and PCB technicians. To start of, a solder paste mixture that has a solder and flux will be applied with a stencil on the fabricated PCB. The components will then be placed in a position and will be held in place with the adhesive of the solder paste. The PCB then will be placed inside the reflow convection oven in order to start its heating process.

The solder reflow process is being based with convection heating, which is similar to home ovens. The temperature of hot air in the oven will follow a thermal profile which then will give the ideal heat and cooling rate on the given solder paste and components. The electronic manufacturers will provide the thermal profile recommendation which serves as an ideal starting point. However, sometimes the thermal profile needs to be modified to get the best possible soldering performance.

Smart or intelligent machines actually demonstrate capabilities in different areas. Reflow ovens are usually the ones that people have relevance the most on the principles.

Reflow ovens are usually thought as the black box because you can’t see it readily or be able to visualize what will happen to the PCB after this disappears inside the oven tunnel and blasting hot air to the boards for the next 8 minutes. The half step to making it transparent would be in making the machine transparent. In a reflow oven, it means a continuous machine that comes with monitoring capabilities in order to provide data for the chosen oven recipe and the actual conveyor speed and zone temperatures and also with the time stamped board and board out, board jam detection and others more. Though this kind of data is useful, it is however insufficient. Smart ovens would need process transparency.

The oven also comes with multiple zones that can be controlled individually for temperature. There are in fact several heating zones followed by cooling zones. The PCB will move through the oven through a conveyor belt, which then is subjected in a controlled time-temperature profile.

Heat sources are usually from ceramic infrared heaters that transfers the heat to the assemblies through radiator. Ovens that use fans to force the heated air to the assemblies are called as infrared convection ovens.

There are some ovens which are designed to reflow PCBs through an oxygen-free atmosphere. Nitrogen is the most common gas that’s used for such purpose. It will help to minimize the oxidation of the surface that will be soldered. The nitrogen reflow oven will take a few minutes in order to reduce the oxygen concentration towards acceptable levels in the chamber. This is why nitrogen ovens usually comes with nitrogen injection at all times that will help decrease the defect rates.

The primary purpose of a reflow oven would be in creating strong solder joints and at the same time adhering on the tolerances that were set by the relevant solder paste, substrate vendors and components. This is to make sure that the oven will produce every assembly in spec, where the PCB thermal profile is measured. For a process transparency, the profile as well as its relationship with the relevant process window should be measured continuously in real-time. In profiling an oven on a periodic basis, the process of the production is running blind and process transparency will be nonexistent.

However, the truth is it is not that hard once you have all the right tips in mind. Outlined below are some of the main factors that you need to consider when looking for a roof restoration company.

Research and Know Your Options
The first step should always be researching. The internet helps you know what all your options are. When you have a list of names to work with, you will know what to search for when researching.

Professional roofing contractors have websites that allow their clients to know a little about the company before they commit. On these websites, you should expect to get information about the kind of services they offer, their location and their contacts. When looking at location, focus on contractors that are located close to where you come from or where you want the roofing project to take place. This will make things easier for you.

Ask for Free Price Quotations
It is important for you to find out about the cost of hiring a roof restoration contractor first before you settle. Knowing the rates from a few contractors can help you compare the prices and in turn, you can decide which one is more affordable based on your budget. As far as prices are concerned, it is good to remember that just because a roofing restoration company has high rates, it does not mean that they offer the best services. Hence, be careful about who you choose.

Look at the Company’s Portfolio
The portfolio is meant to show you some of the projects that the company has handled in the past. When looking at the portfolio, it is good to concentrate on things like the finishing and compare how the roof looks with how it looked before. Roof restoration companies always make a point of having a before and after pictures side by side to show clients their skills. The portfolio should tell you whether you can trust the company enough to hire it or not.

Ask for Referrals
Finally, if the company has the contacts of some of their past clients, you should insist on asking for a few of them. By contacting previous clients, you can get feedback from them about how satisfied they really are with the work that the company handled for them.
