I believe that in the near future, low price halogen-free PCB will be put into the market immediately. In addition, the major board suppliers have also invested more funds in the research and development of halogen-free PCB and halogen-free pp. Halogen-free solder mask and silkscreen inkīecause any contamination of the production process can fail the test. Therefore, the demand for halogen-free PCB has become larger and larger. When drilling halogen-free laminates, some compensation should be made under normal drilling conditions. Therefore, the drilling parameters of ordinary FR-4 are used for Tg materials, the effect is generally not very satisfactory. The Tg point of halogen-free materials is generally higher than that of ordinary copper clad laminates. Chlorine, is found in circuit boards, and is primarily in the form of residual materials left over from production of non-brominated. Fundamentally, halogens in solder paste refer to chlorine and bromine. In addition, in the high-temperature stage, It requires a longer pressing time, generally maintained at 180 ℃ for more than 50 minutes Halogen-Free Solder Paste as the name suggests is a solder paste that does not contain Halogen.
HALOGEN FREE PCB FULL
Take the SY substrate and PP for example, in order to ensure the full flow of the resin and make the bonding force good, this requires a lower sheet heating rate (1.0-1.5℃/min) and multi-stage pressure coordination. Evolving market needs continue to drive forward development of High Frequency printed circuit board.
The first is the lamination parameters, because the sheets of different companies may be different. Among these elements, chlorine, and bromine lead to PCB toxicity. The Printed Circuit Board (PCB or PWB) is the base of electronic products.
These elements are harmful to life and the environment in many ways. Halogen-free PCB Reliability Test and Failure Analysis. The family of halogen elements includes fluorine, bromine, chlorine, iodine, and astatine. Some sections are different from the normal FR4 production IPC-1753-WAM1, Laboratory Report Standard - includes information on Halogen Free. The printed circuit board with no halogen elements is called a halogen-free PCB. The most common halogen-free laminate sheet includes SY11150G, SY1170G, KB6165GC, they are widely used for our customers.
HALOGEN FREE PCB HOW TO
We are able to product halogen-free PCB because we have a production procedure of how to control the materials and the machines.
