3 Dispensing Paths for Dispensing Technology

图片
       PCB are sometimes processed by dispensing machines, which are mainly used for waterproof, dustproof, anticorrosion, and long-term effective protection of PCB and some electronic components that are sensitive to some electronic equipment. In the dispensing process, there are 3 dispensing paths. Do you know which 3 are?   1.  I-shaped Distribution Path The I-shaped dispensing path, also known as the straight-line dispensing path, is suitable for dispensing where a small area is required at the edge of the chip. The length of the dispensing route is generally 50% to 125% of the edge length of the chip. Longer lines can help reduce the curing time of the glue at the edge of the chip, but increase the possibility of trapping some air bubbles, so care needs to be taken to control the amount of glue used.     2.  L-shaped  D ispensing  P ath The L-shaped dispensing path is dispensing along the adjacent two sides of the chip. The glu...

The Difference between PCB Dry Film and Wet Film

Both the dry film and the wet film of the PCB refer to the raw materials used for the Circuit. The dry film is a kind of high-molecular compound. It generates a polymerization reaction after being irradiated with ultraviolet rays to form a stable substance attached to the surface of the plate, thereby achieving the functions of impedance plating and etching. The wet film is a blue viscous liquid synthesized from a photosensitive resin and is added with a sensitizer, a pigment, a filler, and a solvent. The functions of the dry film and the wet film are basically similar. However, if the surface of the PCB is not flat and a very thin film thickness is required, the PCB manufacturers can consider using a wet film. Moreover, the cost of the wet film is much lower than that of the dry film, so that a large amount of cost can be saved. The wet film has a good filling ability, but does not protective film,  so high exposure energy is required. If it is a perforated PCB, the dry fil...

The Difference between PCB and PWB

　　In our daily life, we often use electronic products. A lot of electronic components are used in each electronic product, so we often hear the words PCB and PWB. They are similar but different from the literal point of view, therefore many people are confused. They are not clear whether the PCB and the PWB are the same. Let's explain in detail. 　　The difference between PCB and PWB : 　　PCB: Based on insulating substrate, it means a kind of products on which the wires are connected and components are printed from point to point on a dielectric substrate in a predetermined design. It is the English abbreviation of Printed Circuit Board. 　　PWB:Based on insulating substrate, it means a kind of products on which the wires are connected from point to point on a dielectric substrate in a predetermined design. However, there is no printed component on it.PWBs are the early name of the British, because at that time there were only circuit diagrams on the circuit board, but no printe...
