CHAPTER V. PROCESS INFORMATION

V.1. Delivery

ZE51/61-2.4/SMD modules are delivered in plastic tray packaging, each tray including 50 units. The dimensions of the tray are the following: 329 mm x 176 mm x 5.6 mm. Each unit is placed in a 26.6 mm x 16 mm location. An empty tray weights 45 g and a loaded tray weights around 130 g.

ZE51/61-2.4 RF Module User Guide

1VV0300868 Rev.4 – 31/03/2011

V.2. Storage

The optimal storage environment for ZE51/61-2.4/SMD modules should be dust free, dry and the temperature should be included between -40°C and +85°C.

In case of a reflow soldering process, tiny radio modules must be submitted to a drying bake at +60°C during 24 hours. The drying bake must be used prior to the reflow soldering process in order to prevent a popcorn effect. After being submitted to the drying bake, tiny modules must be soldered on host boards within 168 hours.

Also, it must be noted that due to some components, ZE51/61-2.4/SMD modules are ESD sensitive device. Therefore, ESD handling precautions should be carefully observed.

V.3. Soldering pad pattern

The surface finished on the printed circuit board pads should be made of Nickel/Gold surface. The recommended soldering pad layout on the host board for the ZE51/61-2.4/SMD-WA, is shown in the diagram

below:

All dimensions in mm

1VV0300868 Rev.4 – 31/03/2011

V.4. Solder paste composition (RoHS process)

ZE51/61-2.4/SMD module is designed for surface mounting using half-moon solder joints (see diagram below). For proper module assembly, solder paste must be printed on the target surface of the host board. The solder paste should be eutectic and made of 95.5% of SN, 4% of Ag and 0.5% of Cu. The recommended solder paste height is 180 μm .

The following diagram shows mounting characteristics for tiny integration on host PCB:

V.5. Placement

The ZE51/61-2.4/SMD module can be automatically placed on host boards by pick-and-place machines like any integrated circuit.

ZE51/61-2.4 RF module User Guide

1VV0300868 Rev.4 – 31/03/2011

V.6. Soldering profile (RoHS process)

It must be noted that ZE51/61-2.4/SMD module should not be allowed to be hanging upside down during the reflow operation. This means that the module has to be assembled on the side of the printed circuit board that is soldered last.

The recommendation for lead-free solder reflow in IPC/JEDEC J-STD-020D Standard should be followed.

ZE51/61-2.4 RF Module User Guide

1VV0300868 Rev.4 – 31/03/2011

The barcode label located on the module shield is able to withstand the reflow temperature.

CAUTION

It must also be noted that if the host board is submitted to a wave

soldering after the reflow operation, a solder mask must be used in

order to protect the tiny radio module’s metal shield from being in

contact with the solder wave.

CHAPTER VI. BOARD MOUNTING RECOMMENDATION

VI.1. Electrical environment

The best performances of the ZE51/61-2.4 module are obtained in a “clean noise” environment. Some basic recommendations must be followed:

 Noisy electronic components (serial RS232, DC-DC Converter, Display, Ram, bus ,...) must be placed as

far as possible from the ZE51/61-2.4 module.

 Switching components circuits (especially RS-232/TTL interface circuit power supply) must be decoupled

with a 100 µF tantalum capacitor. And the decoupling capacitor must be as close as possible to the noisy chip.

VI.3. RF layout considerations

Basic recommendations must be followed to achieve a good RF layout :

 It is recommended to fill all unused PCB area around the module with ground plane, except in case of

integrated antenna (no ground plane must be placed in front of the antenna and on the bottom side).

 The radio module ground pin must be connected to solid ground plane.  If the ground plane is on the bottom side, a via (Metal hole) must be used in front of each ground pad.

Especially J28 and J30 (RF Gnd) pins should be grounded via several holes to be located right next to the pins thus minimizing inductance and preventing mismatch and losses.

Example of GND layout Top View (with and without integrated antenna)

ZE51/61-2.4 RF Module User Guide

1VV0300868 Rev.4 – 31/03/2011

VI.4. Antenna connection on Printed Circuit Boards

Special care must be taken when connecting an antenna or a connector to the module. The RF output impedance is 50 ohms, so the strip between the pad and the antenna or connector must be 50 ohms following the tables below. Ground lines should be connected to the ground plane with as many vias as possible, but not too close to the signal line.

CHAPTER VII. ANTENNA CONSIDERATIONS

VII.1. Antenna recommendations

ZE51/61-2.4 performances when used in a product are strongly dependent on the antenna type and its location. Particular cautions are required on the following points:

 Use a good and efficient antenna designed for the 2.4 GHz band.

 Antenna must be fixed in such a location that electronic noise cannot affect the performances. (Outside

location is ideal if available).

 Antenna directivity must be low (Omni directional antenna is usually the best choice).

Recommended antenna specifications:

 Frequency Band : 2440MHz +/- 100MHz

 Radiation Pattern : Omni directional

 Nominal Impedance: 50 

 VSWR: 1.5:1 max.

 Gain: 0dBi

 Polarization: Vertical

1VV0300868 Rev.4 – 31/03/2011

VII.2. Antenna matching

Impedance matching can be required to deliver the maximum possible power from the module to the antenna and vice versa. This is typically accomplished by inserting a matching network into a circuit between the source and the load.

This matching network must be established as close as possible to the ZE51/61 module. Here after an example of matching network between a ZE51/61-2.4 module and an antenna.

VII.3. Antenna types

The following are the antenna examples that may be suitable for ZE51/61-2.4/SMD-WA applications. We distinguish two types of antenna:

 External antenna (antenna is mounted outside of the device)  Embeddable antenna (antenna is integrated inside the device)

VII.4. External antenna

External antenna is recommended when the range performance is primordial. For example, for base stations and access points, where a better antenna gain may be required.

¼ Wave Monopole antenna:

The ¼ Wave antenna is 3 cm long @ 2.4 Ghz. Shorter compensated antennas could be used as long as they are adapted to 2.4 GHz frequency.

Best range may be achieved if the ¼ Wave antenna is placed perpendicular in the middle of a solid ground plane measuring at least 5 cm radius. In this case, the antenna should be connected to the module via some 50 ohm characteristic impedance coaxial cable.

WARNING

The metallic plane must be ideally under the antenna (balanced radiation). Never

short-circuit the hot and cold pins!

The installation directives are the following:

 Solder the coaxial cable on the hot and ground pad antenna (of the ZE51/61-2.4 module.)

 Fix the antenna on a metallic plane or on a metallic box with the metallic screw provided with the antenna.

 If the ZE51/61-2.4 module is integrated in a plastic box, use a metal tape (copper) glued on the plastic

side under the antenna.

ZE51/61-2.4 RF module User Guide

1VV0300868 Rev.4 – 31/03/2011

Half Wave Dipole antenna:

The ½ Wave Dipole antenna is around 6 cm long. In a ½ Wave Dipole antenna the metallic plane is replaced by a second ¼ Wave antenna balancing the radiation.

Half wave monopole antenna typically offers a ground-independent design with favorable gain, excellent radiation pattern. It has a high impedance and requires an impedance-matching circuit (See paragraph IX.3)

WARNING

It is recommended to place the ½ wave dipole antenna away from all metallic

object, which will detuned it.

Particularity it is not recommended to place this type of antenna directly on a

metallic box, but the antenna can be deported away through a 50 Ohm coaxial

cable.

1VV0300868 Rev.4 – 31/03/2011

VII.5. Embeddable antennas

In this section you will find antennas designed to be directly attached to ZE51/61-2.4/SMD-WA module, inside the product casing. These antennas are only used in application where security, cosmetics, size or environmental issues make an external antenna impractical. This type of antenna is used when the integration factor becomes primordial (for mobile and handheld devices) to the range performances.

The basic recommendations are:

 The radio module must not be placed in a metallic casing or close to metallic devices.  The internal antenna must be far from noisy electronic.

Ceramic antenna:

Ceramic antenna is a SMD component to be mounted directly on the PCB. It is designed so that it resonates and be 50 Ohms at the desired frequency. But we recommended to place an impedance-matching circuit (See paragraph VII.2).

The place under and around the ceramic antenna must be free of any track or ground plane. (refer to the antenna constructor requirements). It usually has a hemispherical radiation pattern has described below.

Miniaturized antenna:

This type of antenna features a through-hole feedline to directly attach it to the PCB. This antenna acts like a ¼ wave antenna so that a minimum ground plane is required.

ZE51/61-2.4 RF module User Guide

1VV0300868 Rev.4 – 31/03/2011

ZE51/61-2.4/SMD-IA: Integrated antenna:

ZE51/61-2.4 module is available with an integrated chip antenna, allowing very compact integration for small space application.

Radiation Pattern of ZE51-2.4/DIP board

It is very important to avoid ground plane around and below the antenna, so ZE51/61-2.4/SMD-IA must be implemented as described in paragraph VI.3 and schematics VI.5.
