We at A+B Electronic have more than 50 years of experience in SMT assembly services. We implement your wishes precisely and can guarantee fast processing and delivery thanks to our own parts warehouses on site. We will be happy to discuss your order directly with you. Why should we be your contractor for SMT assembly? We have summarised this here in a few clear words. Or write to us in a few words about what you have in mind for a project – and we'll call you back.
SMT assembly suitable for all order sizes
Three modern production lines are waiting for your order for SMT assembly. During SMT assembly of your PCBs, we first apply the solder paste in a printing process to the pads where the electronic components will later be located. The printing is done by means of a special stencil or with a jet printer. The circuit boards are then assembled by machine and then soldered. Soldering takes place in the standard process in a reflow oven. For prototypes or special technologies, we also use our vapour phase.
Your technological advantages with A+B Electronic
- Whether prototype, small or large series in SMT assembly: We implement your idea through our precise industrial manufacturing.
- High component mix? It’s no problem for us, of course. We plan the assembly efficiently.
- We test the technical feasibility of your order in advance.
- We optimise the design for efficient industrial production of your PCBs. We’re happy to work closely with your developers to achieve this.
- We plan material logistics for the long term through international purchasing and efficient on-site warehousing.
PCB assembly has special requirements today: We install components in a large mix and in ever smaller sizes. Some components are no longer visible to the naked eye, and the assembly of PCBs is sometimes modernised on a monthly basis. This is also a challenge in SMT production.
“Miniaturisation is a trend in SMD assembly – so more and more components can be installed per PCB.”
SMT production – A+B Electronic in the video
We can process even the smallest components on our modern production lines:
Ultra-precise assembly platform from Fuji
Among the pick-and-place machines, A+B Electronic has acquired the highlight: the Fuji 7x NXT2. The hybrid pick-and-place machine works with the utmost precision and guarantees a safe and fast process for placing SMD components.
SMD or SMT assembly – What’s the difference?
SMD is the abbreviation for surface mounted device.
SMT stands for surface mounted technology. SMT refers to the entire technology of mounting and soldering electronic components such as resistors, capacitors, transistors, integrated circuits onto a printed circuit board.
The individual steps of SMT assembly are:
- Applying or printing on the solder paste
- Placing the components on the circuit board
- Soldering in the reflow oven
- Automatic Optical Inspection (AOI)
Both terms are used synonymously in practice.
Our SMT testing process: AOI & Revision
Rigorous quality control is a matter of course for us. We carefully check all PCBs after SMT production. This includes an Automatic Optical Inspection (AOI). If necessary, our employees rework to ensure that only flawless parts reach you or your customers directly. Read more about our quality assurance here.
SMD components at a glance
SMD components include passive components such as resistors, capacitors, induction coils. There are also integrated circuits and active components. We also install plugs and switches as SMD components on printed circuit boards.
We apply special protective coatings
We carefully coat the assembled PCB with a special protective lacquer. It optimally protects electronic assemblies against condensation, humidity and contamination. In order to be able to offer the complete package for your assemblies, we paint according to your specifications in a casting process with our selective painting machine from Asymtek. Read more about our conformal coating here.
We deliver – also directly to your customers
With our delivery service, you can decide whether we send the assembled PCBs to you or directly to your end customer. Assembled PCBs are sometimes very sensitive and there are a number of things to consider when shipping them. That is why we offer you specific packaging concepts and ship the assemblies in ESD packaging, for example. So you can outsource the logistics to us with peace of mind, and we use all our expertise and routine in the field of logistics and complete assembly.
We advise after the pilot series – and think your product idea further ahead
SMT assembly is teamwork. That’s why consultation within the scope of product development is a matter of course for us. Because even if the counselling and a share for development is not part of the project: If we notice something about the assembly, or if we have a bellyache about an arrangement, we’ll get in touch with you immediately. We think along with your project.
This is a great advantage, especially for zero series. Once you’ve tested the series in practice, we’ll be happy to sit down together to look for ways to optimise it. This allows us to react flexibly to new requirements in our production. It’s about regularly recurring orders? Then you can rely on us to proactively approach you to ensure the availability of all components without waiting times.
