We assemble electronic subassemblies on production lines or in a specialized stands system. The choice of assembly method depends on the volume of the production and the economics of the process.
Our experienced team of production engineers know the subassemblies being implemented, models and balances the assembly process, selects the optimal number of assembly stand. We develop instruments that facilitate and accelerate the assembly process. We make instruments ourselves, which allows us to minimize costs.
To minimize production costs, ensure repeatability of the assembly process and its highest quality, each production stand is equipped with pneumatic and electric tools (pneumatic screwdrivers, air ionizers, glue dispensers, silicone dispensers, etc.).
The assembly of subassembly is usually divided into stages:
- assembly,
- functional testing of the subassembly,
- packing,
- final inspection.
The subassemblies are assembled directly on the production line. The parts are delivered in containers protected against ESD, easily available to employees.
The assembly process is monitored and verified by the employees of the quality control department. All assembled subassemblies are registered in the electronic database, so that the history of the assembled subassembly can be replayed at any time.
When the assembly on a production line is unprofitable, the subassemblies are assembled in a specialized stands system. The organization of the specialized stands assembly system is adapted to the specifics of the subassembly. The stands in the specialized stands system are equipped similarly to the stands of the production line. The assembly process in the specialized stands system is also monitored and recorded in an electronic database.
The assembly of PCB’s in THT technology takes place in our location on the Universal family machines, while the SEHO soldering machine is used for mechanical soldering. We perform the assembling in SMD technology, in cooperation with several proven Polish companies that have modern, very efficient automated production lines. We use modern stations of integrated circuit programmers as well as PCB’s for writing control programs and firmware. In the production of electromechanical subassemblies we use dedicated testers made by us to check the functionalities of subassemblies and to measure the indicated mechanical and electrical parameters.
Examples of solutions
Keyboard
It is assembled on a cheaper one-sided PCB plate, using high quality microswitches with high reliability of switching and automatic soldering. The keys made of ABS have inscriptions made in pad printing technology, in one cycle, using a collective stamp. This technology ensures very good legibility despite small pictograms, high resistance to abrasion and the adverse effects of many cleaning agents used during operation.
LCD display module
It consists of two electronic PCB’s assembled on double-sided PCB plates using three assembly technologies: SMD, THT, manual assembly. A combination of two PCB’s with a rigid tape from several wires was used . This solution enables the use of this unit in various casings and eliminates the need for additional connectors and wire bundles.
Turned parts and subassemblies in which they are used
Made of various class, shapes and diameters of rods as in automatic or conventional turning technology. Suitable surface coatings are used: nickel plating, anodizing, tin plating and galvanizing. The example presents the use of turned elements for the construction of electromagnets and a set of retractors for which accuracy of up to a hundredth part of a millimetre as well as and high quality and durability (class) of the surface are required.
Special external electronic cables
Connections of cables with terminals are made and soldered manually in accordance with ROHS or in the technology of crimping pins on the automatic machine, based on appropriate applicators. High-class electronic materials compliant with ROHS and from reliable suppliers were used. At the end of the production process, each of the cables made is tested in accordance with its intended use.
Connecting bundles
Made of single wires prepared on a automatic machine for cutting wires. Used to connect: PCB’s, strain gauges, and other components. High quality of workmanship ensures reliable operation of devices during operation and easy servicing.
External power cable
Made by hand-soldering technology in accordance with ROHS. In connection with the attested power supply, it is used to connect certain finished products to the power network. In the presented model, it is used to connect a professional music device. The use of high-quality materials ensures the reliability of the devices powered by this unit.
