First, according to the use effect to judge the quality of smt red glue two, according to the welding situation to see smt red glue, three, according to the word of mouth to judge smt red glue, and the best way is to try
How to choose SMT patch processing machine: first, accuracy, second, stability, third, durability, fourth, easy maintenance
There are many procedures to be paid attention to in SMT patch processing, especially solder paste printing. But there are a lot of issues that are important but not being noticed.
As an important part of PCBA, SMT processing has a direct impact on product quality. SMT processing includes multiple processes. How to standardize each process so as to post perfect PCBA
The heat declared by the equipment must be removed by heating, ventilation and air conditioning equipment, which will require double power. In the welding is directly affixed to the surface of the printed circuit board, the electrode is welded to the same
1, lead-free solder paste printing, lead-free solder paste printing, 2, small material mounting this process uses the machine is CP machine, 3, large material mounting this process uses XP machine,4, furnace QC, 5, reflow soldering reflow is to melt the s
It is necessary to check regularly whether the power supply on the SMT patch processing line has done all kinds of safety protection, and also to do special training on power supply protection. In the SMT patch processing and production process, it is nec
1. Establish a total quality (TQC) network within the enterprise to provide timely quality feedback.Two: In order to ensure the accurate inspection and maintenance of testing equipment and equipment, it is necessary to inspect and maintain the products, t
How to use SMT solder paste to clean the solder spot first, pay attention to wipe very clean, do not have any residue, otherwise it will affect the next work, the solder paste opening time as short as possible, in the process of use, roughly estimate the
In the operation, electrostatic protection is a very important work, can not be careless, we should do several points: 1, ground wire, 3, the use of ion fan, 4, cleaning, 5, warning signs, 6, the use of part of the equipment, need written consent, seven,
Is the use of AOI, to ensure the inherent quality of SMT products, while parametric automatic optical detection device to fill this gap, whether you choose image comparison for low capacity mount, or choose parametric mount for medium-high capacity mount,
