Depaneling
As a benefit of a total PCB is referred to in the electrical connection technology, which consists of individual PCBs and not yet separated. Here, the total PCB contain several times identical circuit functions with the same design or it can be different circuit functions are on the individual circuit boards. A production benefits includes at least two individual circuit boards. The device for separating the printed circuit boards is referred to as a resource separator.
PCB manufacturing
Several individual circuit boards - as later the carrier to be equipped devices - are arranged side by side on a large board at Benefits Design and manufactured in the composite. If the production benefits in the assembly are smaller than production use in the preparation of the support, is separated before the assembly in manufacturing benefits, which contain a smaller number of individual printed circuit boards.
Manufacturing steps of the production modules
The production benefits be equipped as a composite of several individual circuit boards simultaneously by the placement machine with SMD components. Furthermore, production benefits are used in the field of mechanical or manual placement of THT components and other processes of construction and connection technology. After one or two soldering ( reflow soldering, vapor phase soldering, wave soldering or selective soldering ), and all for editing in the overall benefits provided for other processes ( automated optical inspection, in-circuit test ) the total circuit board is separated into individual PCBs.
Separation processes
After the processing of all manufacturing steps, which are designed for processing the entire benefit the overall printed circuit board is disconnected. For this purpose, different separation methods are available: The total PCB (total assembly ) is free milling, manual breaking (manual cutting of the crushing places ), tool bound severing punching locations by mechanical punching or manual or mechanical cutting of Ritz points by a circular blade, scissors, knives or parallel knife into individual circuit boards (single modules ) separately. The interconnected components: PCB is referred to as a whole as a production benefit, therefore, the name comes depanelization.
Advantages and Disadvantages
The advantage of the simultaneous production of so-called production benefit is a higher throughput rate at the plant, as per benefit only a single transport process and action is required. The benefit processing increases the efficiency in the automated manufacture of printed circuit boards and electronic assemblies. Further may be produced by manufacturing benefits circuits in which a single circuit board is smaller than the minimum for mechanical assembly.
A drawback of the benefit separation is the possible damage to the components or of the assembled components, such as ceramic capacitors due to improper cutting. In addition, performs a defective item PCB, which can not be economically repaired, an additional expense: either all good is discarded or further processed with the defect and segregated only the defective item PCB after separating. In the latter case, the placement of the defective item printed circuit board can be omitted, but this necessitates a corresponding control of the assembly by reading a label.
