Do not place metal obj ects or r oute ar ound the antenna 2mm, it is r ecommended to hollow out the under side of the antenna. As metal has a shielding ef f ect on electr omagnetic signals, tr y to avoid using metal enclosur es.

4.2 Power Suppl y Desi gn
Note: MS-BTD020R-L Bluetooth module has cer tain r equir ements f or the power supply cir cuit. The r ipple coef f icient of the 3.3V supply voltage should be less than 200mV, the minimum output cur r ent should be gr eater than 20mA (the choice of the 3.3V r egulator needs to be deter mined by the actual cir cuit cur r ent).
4.3 Layout Gui del i nes
It is str ongly r ecommended to use good layout pr actices to ensur e pr oper module oper ation, placing copper or any metal close to the antenna will af f ect antenna per f or mance and thus deter ior ate antenna ef f iciency. The metal shielding ar ound the antenna will stop the signal f r om r adiating, ther ef or e metal enclosur es should not be used with the module, please use mor e gr ound over holes at the edge of the gr ounded ar ea, the f ollowing r ecommendations will help to avoid EMC pr oblems in the design.
Please note that each design is unique, the f ollowing descr iptions do not take into account all basic design r ules, such as avoiding capacitive coupling between signal lines; the f ollowing descr iptions ar e intended to avoid EMC pr oblems caused by the RF par t of the module and should be consider ed with car e, to avoid pr oblems with the digital signals in the design. Ensur e that the loops of the signal lines ar e as shor t as possible.
E.g.: If the signal enter s the inner layer via the thr ough-holes, always use gr ound thr ough-holes ar ound the pads. And place them closely and symmetr ically ar ound the signal thr ough-holes. Any sensitive signal r outing and loops should be done on the inner layer of the PCB as f ar as possible. Sensitive signal lines should have a gr ound sur r ound above and below them. Make sur e that the r etur n path is the shor test possible (e.g. use a gr ound wir e next to the signal wir e).

5 Pr oduct Tr eat ment
5.1 St or age Condi t i ons
Pr oducts sealed in moistur e-pr oof bags (MBB) should be stor ed in a non-condensing atmospher e at 40 °C/90% RH. The module has a moistur e sensitivity class MSL of 3. Af ter unpacking the vacuum bag, it must be used within 168 hour s at 25±5 °C and 60% RH, other wise it needs to be baked bef or e it can be put on line a second time.
5.2 Baki ng Condi t i ons
Modules must be baked at 120+5°C f or 8 hour s, the second-baked module must be solder ed within 24 hour s af ter baking, other wise they must still be stor ed in the dr ying oven.
5.3 Ref l ow Sol der i ng
Bef or e any r ef low solder ing is car r ied out, it is impor tant to ensur e the modules ar e packaged in moistur e-pr oof package. The package contains a desiccant (to absor b moistur e) and a humidity indicator car d to show the level of dr yness to be maintained dur ing stor age and shipment. If it is necessar y to bake the module, please check the table below and f ollow the instr uctions specif ied in IPC / JEDEC J-STD-033.
www.mesoonrf.cn
Page8
Note: The tr ay must not be heated above 65°C. If the high temper atur e baking method (above 65°C) in the table below is used, the module must be r emoved f r om the tr ay. Any module that has been unpacked and not sur f ace mounted within a specif ied time should be r epackaged. Ef f ective desiccants and humidity indicator car ds should be placed inside the package. MSL (moistur e sensitivity level) 3 modules should be stor ed in the air f or less than 168 hour s at an ambient temper atur e of 30°C / 60% RH. The r ecommended baking time and temper atur e ar e as f ollows: The design of sur f ace mount modules is easy to manuf actur e, including r ef low solder ing to the PCB main boar d. Ultimately, it is the r esponsibility of the customer to choose the appr opr iate solder paste and ensur e that the f ur nace temper atur e dur ing r ef low meets the r equir ements of the solder paste. Sur f ace mount modules conf or m to the J-STD-020D1 standar d f or r ef low solder ing temper atur es. The solder ing conf igur ation f ile depends on the var ious par ameter s that need to be set f or each application. The data her e is only used f or r ef low solder ing guidance.
Pr e-heat zone (A) – This zone is heated up at a contr olled r ate, typically 0.5-2°C / s. The pur pose of this zone is to pr eheat the PCB boar d and components to 120 to 150°C. This stage is r equir ed to distr ibute the heat evenly acr oss the PCB boar d and to completely r emove the solvent to r educe ther mal shock to the component.
www.mesoonrf.cn
Page9
Equilibr ium Zone 1 (B) – Dur ing this stage the f lux becomes sof t and evenly encapsulates the solder par ticles and spr eads them acr oss the PCB boar d to pr event them f r om being r e-oxidized. As the temper atur e incr eases and the f lux liquef ies, each activator and r osin is activated and begins to r emove the oxide f ilm that has f or med on each solder pellet and the PCB boar d sur f ace. For this ar ea, temper atur es of 150° to 210° and times of 60 to 120 seconds ar e r ecommended. Equilibr ium zone 2 (C) (optional) – To solve the pr oblem of upr ight par ts it is r ecommended to keep the temper atur e at 210 – 217 f or appr oximately 20 to 30 seconds. Ref low zone (D) – The cur ve shown is designed f or Sn / Ag3.0 / Cu0.5. It can be used as a r ef er ence f or other lead-f r ee solder s. The peak temper atur e should be high enough to achieve good wettability, but not so high as to cause discolor ation or damage to the component. Too long a solder ing time can lead to inter metallic gr owth which can r esult in br ittle solder j oints. The r ecommended peak temper atur e (Tp) is 230 to 250°C. At temper atur es above 217°C, the solder ing time should be 30 to 90 seconds. Cooling Zone (E) – The cooling r ate should be ver y f ast to keep the solder gr ains small, which will pr ovide a longer lasting solder j oint. A typical cooling r ate should be 4°C.
