HJ-380IMH 4 Welding Method Reflow soldering is recommended for welding. HJ-380IMH module use high temperature resistant materials, Manufacturing by Lead-free Process. The maximum temperature resistance is 265℃. Ten continuous reflow soldering has no effect on properties and strength. Specific parameters as shown in Table 5-1. Table 5-1 Reflow soldering parameters Parameter Value Features Lead-free process Average ramp up rate(TSMAX to Tp) 3℃/sec.
HJ-380IMH 5 Supply Information Packaging method Packaging with tapes and reel. Sealed with chip-level anti-static aluminum foil bag, each bag contains desiccant, use industrial grade vacuum machine to ensure airtight, moisture-proof, waterproof and dustproof (IP65). The actual packing effect is shown in Figure 6-1. Figure 6-1 External Packing Image All packages will be labeled with goods information. All packages will be marked with the cargo information, including ROHS and anti-static signs.
HJ-380IMH 6 FCC Warning (OEM) Integrator has to assure compliance of the entire end-product incl. the integrated RF Module. For 15 B (§15.107 and if applicable §15.107) compliance, the host manufacturer is required to show compliance with 15 while the module is installed and operating. Furthermore the module should be transmitting and the evaluation should confirm that the module's intentional emissions (15C) are compliant (fundamental / out-of-band).
HJ-380IMH 2) The module has buffered modulation/data inputs to ensure that the device will comply with Part 15 requirements with any type of input signal. 3) The module contains power supply regulation on the module. 4) The module contains a permanently attached antenna. 5) The module demonstrates compliance in a stand-alone configuration.
