The hottest hardware terminal manufacturer in Fosh

Foshan hardware terminal manufacturer

SMT lead element welding method: when starting to weld all pins, solder should be added to the tip of the soldering iron, and all pins should be coated with flux to keep the pins moist. Touch the end of each pin of the chip with the tip of a soldering iron. Foshan hardware terminal manufacturer_ Cairun industry, until it saw solder flowing into the pin. During welding, keep the tip of the soldering iron parallel to the soldered pin to prevent overlap due to excessive soldering

after soldering all the pins, soak all the pins with flux to clean the solder. Absorb the remaining solder where necessary, Foshan hardware terminal manufacturer_ Cairun industry to eliminate any short circuits and laps. Finally, use tweezers to check whether there is faulty soldering. After checking, remove the flux from the circuit board. Foshan hardware terminal manufacturer_ Cairun industry, dip the hard brush with alcohol and wipe it carefully along the pin direction until the flux disappears

1. Analysis of the shape of the plastic part of the battery buckle

the structure of this plastic part is relatively simple and the appearance is smooth, but the demoulding involved in the groove of the product is necessary to be twice ejected, and there are four slots on the plastic part

2. Analysis of the data of the battery buckle

the data of the battery buckle is PE, which is the abbreviation of polyethylene. It is a polymer polymerized by ethylene. When used as a plastic, its uniform relative molecular weight should be more than 10000. According to different polymer conditions, the high efficiency of plastic extruder is mainly reflected in high output, low energy consumption and low manufacturing cost. The practical uniform relative molecular weight can range from 10000 to millions. Most of the PE ethylene monomers produced are obtained from petroleum cracking. Polyethylene is one of the resins with the simplest molecular structure. It has rich sources of raw materials, low price, excellent electrical insulation and chemical stability, easy to form and process, and many kinds, which can meet different performance requirements. Therefore, it has developed rapidly since its inception. It is now the largest resin type with the largest output and is widely used

pe data performance characteristics:

soft, poor mechanical properties, low surface hardness, good chemical stability, but not resistant to strong oxidants, good water resistance

PE molding characteristics:

do not preheat before molding, shorten large, easy to deform, long cooling time, low molding efficiency, plastic parts with shallow side concave can be forcibly demoulded

II. Check the meta equipment before mounting:

(1) pick up materials (PCB, meta equipment) and check according to the mounting schedule of product process documents

(2) as for the PCB that has been opened, we need to clean and bake it according to the length of the opening time and whether it is affected by moisture or pollution

(3) for the equipment with moisture-proof requirements, check whether it is damp, and remove the damp on the damp equipment. After unpacking, check the humidity display card attached to the package. When the indicated humidity is more than 20% (read at 23 ℃ ± 5 ℃), it indicates that the equipment is now damp, and the damp equipment should be dehumidified

smt chip processing manufacturers - two advantages of SMT chip processing

smt chip processing plays a vital role in the development of industry. SMT assembly density is high, electronic products are small in size and light in weight. The volume and weight of SMT chip components are only about 1/10 of traditional plug-in components. Generally, after selecting SMT, the volume of electronic products will be reduced by 40%~60%, and the weight will be reduced by 60%~80%

? SMT patch processing

1. Efficiency and low cost

smt patch processing is easy to complete automation, improve production power, save materials, energy, equipment, manpower, time, etc., reduce costs by 30%, and have the advantages of electro-hydraulic servo experimental machine force, displacement, deformation control ~50%

2. The volume of electronic products is small

the volume of chip components is only about 1/10 of that of traditional plug-in components. Generally, after SMT chip processing, the volume of electronic products is reduced by 40%~60%
