4 1. Introduction The aim of this document is to propose several recommendations about addlink radio module integration in order to perform successful addlink integration, i.e. to cover different aspects such as standards compliancy and integration cautions (i.e. power supply, antenna, process). It also aims to help the customer with his addlink integration by detailing several and various recommendations and by proposing different services. After a presentation of the main R&TTE directives concerning compliance, technical documentation and labelling requirements for products integrating radio modules such as addlink, recommendations and cautions about conception and integration (i.e. hardware recommendations) and about the manufacturing process (i.e. storage, soldering process) are listed and detailed in a second chapter, including demonstration schematics. The third and last chapter will then conclude on a recap of the main directives and includes a list of check points describing what the customer has to fulfil to avoid re-certification of the final product integrating addlink radio module. It also presents different services that can be provided by Adcon RF Technology in order to help the customer with his integration. 2. R&TTE Directives: Technical Guidance Note This chapter just quotes the whole Technical Guidance Note on Requirements for a Final Product that Integrates an R&TTE Directive Assessed Radio Module from R&TTE compliance association.

9 3. ADCON Recommendations 3.1 Conception and integration Antenna An important part of the antenna forms the ground plane underneath the antenna. Because the ground plane is not part of addlink itself but must be provided by the host PCB, and because the ground plane has influence on the antenna polarisation, thus on the antenna performances, special care is needed during the design of the host PCB. Best performance is reached when the polarisation of both transmitting and receiving units are identical. The best polarisation for an application depends on the placement of the addlink radio modules. In general, two alternative situations can be distinguished: If both addlink modules operate at the same height, optimal range should be realised when the antennas of both modules are horizontally polarised. If one addlink module is located above a second one, optimal range should be realised when both modules are vertically polarised. To reach optimal performances, experiments with different ground plane dimensions have been performed. The table below states optimal configurations of addlink module s antenna: W2 L1 addlink with integrated antenna L2 W1 groundplane VERTICAL POLARISATION L2 > 50 mm W1 =10 mm G > -5 dbi W2 = 10 mm L1 = 10 mm L2 > 70 mm G > -4 dbi HORIZONTAL POLARISATION W2 = 10 mm L1 = 10 mm L2 = 10 mm W1 > 50 mm G > -4 dbi W1 > 70 mm G > -2 dbi Page: 9

10 Nevertheless, W1 and L2 values can be decreased or increased for the addlink radio module to be integrated in given applications. The following diagram shows the gain s evolution when W1 and L2 are increased (10 to 70 mm) and summarise the characteristics of the antenna: Gain in dbi L2 in mm W1= 10 mm W1 = 30 mm W1 = 50 mm W1 = 70 mm The diagram clearly shows that the gain increases with W1 and L2. Therefore, the longer W1 and L2, the better the antenna s electrical performance will be. Actually, the polarisation also needs to be considered, i.e. a proper W1-L2 combination needs to be chosen to get the desired polarisation (vertical or horizontal). Finally, when the integrated antenna is used, the addlink radio module should not be placed in a metallic casing or close to metallic devices. Page: 10

11 3.1.2 Power Supply The power supply for switching circuits (especially the RS-232/TTL interface circuit) must be decoupled with a tantalum capacitor as close as possible to the switching circuits. An LC filter (see picture below) must be placed as close as possible to the addlink power supply pins, i.e. radio part power supply (V CC or addlink pin 14) and digital power supply (V DD or addlink pin 23). Supply voltage from host L1 C1 C2 addlink Vcc = pin 14 & Vdd = pin 23 Recommended values for LC filter Symbols Reference Value Manufacturer L1 LQH1C1R0M04 1µH Murata C1 GRM235Y5V226Z10 22µF Murata C2 Ceramic CMS 25V 100nF Multiple The addlink ground pins must be connected to a solid ground plane. If the ground plane is on the opposite side, a via must be used for each ground pin of addlink. Page: 11

15 3.2 Process Information Delivery addlink modules are delivered in plastic tray packaging, each tray including 42 units. The dimensions of the tray are the following: 340 mm x 240 mm x 15 mm. Each unit is placed in a 22 mm x 40 mm location. An empty tray weights 76 g and loaded trays weights from 220 to 270 g depending on the addlink type. Trays are delivered in carton boxes, each box including 15 trays. The dimensions of the box are the following: 360 mm x 250 mm x 170 mm. An empty box weights around 430 g. Page: 15

16 3.2.2 Storage The optimal storage environment for addlink radio 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, addlink 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, addlink modules must be soldered on host boards within 168 hours. It has also to be noted that due to some components, addlink radio modules are ESD sensitive device. Therefore, ESD handling precautions are to be carefully observed Soldering pad pattern The surface finish on the printed circuit board pads should be either made of Nickel/Gold or can be a flat Tin/Lead surface. For optimal performances, the host board will need a maximum ground plane so that the integrated antenna becomes less sensitive to the environment. The recommended soldering pad layout on the host board, as well as the host board cutout for addlink integration are shown in the diagram below: Page: 16

17 3.2.4 Solder paste addlink radio 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 63% of tin and 37% of lead. The recommended solder paste height is 200 to 250 m (8 10 mil). The following diagram shows mounting characteristics for addlink integration on host PCB: solder dot host PCB Cut out on host Integrated antenna addlink module SMD area brace solder dot host PCB Cut out on host z Placement addlink radio module can be automatically placed on host boards by pick-and-place machines like any integrated circuit with the following recommended parameters: Placing accuracy: +/- 90 µm minimum Nozzle diameter: 5-6 mm Vacuum pressure: 9.10 mm Application area: Geometrical centre of addlink antenna Soldering profile It must be noted that addlink radio 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 reflow process should be a regular surface mount profile. The ramp up speed should not exceed 3 C/s, reaching a peak temperature of 210 to 225 C during 10 to 20 seconds. The maximum sloping rate should not be higher than 4 C/s. 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 addlink radio module s metal shield from being in contact with the solder wave.

18 3.2.7 Marking The addlink demo kit, containing the addlink board, has successfully passed the tests according to the EN (2000 edition) standard as well as the electromagnetic compatibility tests according to the EN (2000 edition) standard. The addlink board is therefore entitled to the CE marking according to the Directive 1999/5/EC on radio equipment and the mutual recognition of their conformity. The notified body is the Emitech laboratory, France. The B-868-addLINK-NB-A-MC, part number , includes a specific marking with the CE0536 logo added to the serial number and barcode sticker. This logo indicates that the product has been successfully tested according to the required standards. The other addlink versions do not include any logo. A.

19 4. Conclusion regarding R&TTE Directives 4.1 Recap of main R&TTE directives This paragraph summarises the different guidance edited by the R&TTE compliance Association. The whole guidance note is available in the first chapter. Conformity Assessment to the Essential Requirements of the Directive Assessed radio modules (i.e. addlink) installed in equipment in conformance with the manufacturer's installation instructions require no further evaluation under Article 3.2 of the R&TTE Directive and do not require further involvement of a R&TTE Directive Notified Body for the final product. In all other cases, or if the manufacturer of the final product is in doubt then the equipment integrating the radio module must be assessed against Article 3.2 of the R&TTE Directive. In all cases assessment of the final product must be made against the Essential requirements of the R&TTE Directive Articles 3.1(a) and (b), safety and EMC respectively, and any relevant Article 3.3 requirements. In the case where integration of a radio module requires assessment involving the submission of a TCF to a Notified Body and the module manufacturer has not made his technical documentation available to the product manufacturer, the module manufacturer must, on request, make the module documentation available directly to the Notified Body. It is not required that the final product manufacturer's TCF include the module manufacturer s proprietary documentation. In any event the final product manufacturer should ensure that the build status of the module integrated is known. This could take the form of a model and issue number, or a list of drawing numbers with issue numbers and date. Technical Documentation The final product manufacturer, his authorised representative or person first placing the final product on the community market, must ensure that the module manufacturer is aware that all documentation pertaining to the module must be supplied, on demand, either directly or via the final product manufacturer themselves, to the relevant national authority of any Member States as required by the R&TTE Directive. Notification In the case where a Notified Body/Bodies has/have assessed the final equipment this will be the Notified Body number(s) given on the notification to the Spectrum Management Agencies. In the case where a Notified Body has not assessed the final equipment the Notification can be made to Spectrum Management Agencies using the Notified Body number(s) on the radio module. Marking Where a radio module is placed on the market in its own right, it will carry the CE marking and, where appropriate, the number of any NB involved. The final product must carry CE marking to show compliance with all the directives that are applicable to it. The numbers of all the NBs involved in every aspect of the conformity assessment must be shown next to the CE Marking with any additional marking such as the Alert Symbol alongside. The technical documentation will show the role of each NB. Repetition of the CE symbol itself should be avoided wherever this is practicable. Page: 19
