At the same time, ensure that all mechanical and electrical specifications and module certifications are maintained. The design should be carried out within the scope of the physical dimensions of the machinery as shown in Figure 4-2. All measurements are in millimeters (mm). 4.3 Precautions The module uses an external antenna, which is far away from metal devices as far as possible. Module reading distance is closely related to antenna size and card size, please adjust accordingly according to actual needs; Try to avoid touching the electronic components on the module without protective measures to reduce the possibility of electrostatic damage to the module. 4.4 Refer to PCB packaging Figure 4-3: Reference package dimensions 5. Reflux parameters are recommended Reflux parameters can refer to the following Settings: Figure 5-1: Backflow recommendation curve Temperature range Preheat zone(<150) Uniform temperature zone(150- 200) Recirculation zone(>217) Cooling zone Time 60-120S 60-120S 40-60S Ramp down rate:1/sSlope4/s Key parameters Ramp up rate:2S Ramp up rate:<1S Peak:240-260 Table 5-1: Recommended parameters for reflux 6.
