No cleaning means that the residues of PCB circuit boards are safe from the chemical point of view, will not have any impact on the production line of PCB circuit boards, and can be left on PCB circuit boards
In PCBA processing, there are several process points in the whole process of rework and reflow: 1. Repair reflow welding curve should be close to the original welding curve. 2. In the reflux process, the heating temperature and time of each area should be
The following factors should be considered in the processing of PCBA capacitor components: first, the selection of capacitor voltage resistance, second, capacitance selection, third, capacitor medium selection,
Prevention can be carried out in the following ways: 1, moisture-proof storage of components, 2, choose well-known brand solder paste, 3, adjust printing parameters, 4, adjust reflow temperature curve, 5, try to use reflow welding, reduce manual welding,
The following operations will be carried out in the maintenance technology: 1, inspection of components, 2, welding state analysis, 3, detection of components direction, 4, tool inspection of components, 5, power-on test
So what are the factors that affect the price of a PCB board? 1, PCB material difference, 2, surface treatment process difference, 3, PCB itself difficulty difference, 4, copper foil thickness difference, 5, customer quality acceptance standard difference
The quality control of the whole pcba process is very important. 1.PCB circuit board manufacturing; 2.PCBA incoming components procurement and inspection; 3.SMT patch processing; 4. Plug-in processing, 5. Program burning, 6.PCBA board test
What are SMT patch, PCB circuit board, PCBA processing and DIP plug-in respectively? First, SMT is one of the basic components of electronic components, which is called surface assembly technology; second, PCB is the most important component of electronic
To repair and maintain the internal circuit board, the following maintenance methods are: 1, inspection components, 2, welding state analysis, 3, component direction detection, 4, tool inspection of parts, 5, startup test
Analysis of PCB deformation causes :1. The uneven area of the copper plane on the circuit board will aggravate the bending and warping of the circuit board. 2. The weight of the PCB board itself may also cause the board to sag and deform.
Five general types of PCB circuit boards: single-sided circuit boards, double-sided circuit boards, multilayer circuit boards, rigid circuit boards, flexible circuit boards
Enterprises should pay attention to the circuit board proofing and proofing manufacturers of engineers and operators for good communication, and in the delivery of proofing materials when carefully check the relevant documents.
