connectBlueCopyright © 2010 connectBlue AB Page 23 of 341. 2. Tolerances:Outline dimensions +/- 0.1mmDrilled hole to outline: +/- 0.05mm5.1.1 Mounting holesThere are 2 x 2.3mm mounting holes on cB-0942. The reasons for the 2.3mm holes are that the threaded M2 holes on the single anddouble row connectors (see section 4.2.1) are not aligned. The outer tangents of the 2.3mm holes align the module if the single rowconnectors are used and the inner if double row connectors are used (see Figure 11).Choose the outer tangent (CC distance 27.24mm) if the module is aligned and mounted with some other technique based on M2 screws(e.g. press-fit nuts), see Figure 12.
connectBlueCopyright © 2010 connectBlue AB Page 24 of 345.2 Using the J2/J3 board-to-board connectorsThe board-to-board connector should be a 1 mm pitch one-piece part connector. The recommended manufacture is Samtec with manyconnector options available; see section 4.2.1.1.Chapter 2 contains more information about the connector and the electrical interface.5.2.1 Suitable one-piece part connectors5.2.2 Double row ASP-118580-01 / ASP-118581-01 connectorsThis connector is a double row connector and connects both J2 and J3. It connector has a height of 3.0 mm and this has to beconsidered if components are to be mounted on the motherboard under the board. The connector is also available with a height of 6.0mm and 10.0 mm (The FSI-120 serie from Samtec).There are alignment pins on the bottom side of the connector.The connector is available with M2 threaded inserts (ASP-118580-01) that fit the mounting holes on the board. You may screw the boarddirectly into these inserts. If you want to have a tighter and more secure mounting you may use longer screws and secure it using a nuton the backside of the motherboard.Another way to mount the module is to use press-fit nuts on the motherboard and skip the M2 threads on the connector(ASP-118581-01), see section 4.3 for more information about press-fit nuts.Samtec ordernumber Quotenumber Equivalent part Package RemarkREF-120021-01 55392 FSI-120-03-G-D-AB Tube Align pin on bottom side onlyREF-120021-02 55392 FSI-120-03-G-D-AB-K-TR Tape-n-Reel Align pin on bottom side onlyREF-120018-01 55392 FSI-120-03-G-D-M-AB Tube With M2 threaded inserts and align pin on bottomside onlyREF-120018-02 55392 FSI-120-03-G-D-M-AB-K-TR Tape-n-Reel With M2 threaded inserts and align pin on bottomside onlyWhen ordering connectors from Samtec or an official Samtec distributor, please use the REF order number and refer tothe connectBlue global quote number for best price. For technical questions regarding the Samtec connectors pleasecontact connectBlue or Samtec at Scandinavia@samtec.com.See figure below for more information about the connector and necessary measurements on the motherboard. The large mounting holeson the motherboard are designed for press-fit nuts and could be smaller if press-fit nuts are not used.
connectBlueCopyright © 2010 connectBlue AB Page 25 of 345.3 Using press-fit nuts for mountingA press-fit nut is pressed into the PCB from the bottom side with a special press tool. M2 sized press-fit nuts are suitable for the modules(see figure below) and are manufactured by PEM Fastening Systems, , part no KFS2-M2. Be careful with the distancewww.pemnet.combetween the nuts regarding alignment.Spacer-pipes are recommended to use between the PCBs when press-fit nuts are used.
connectBlueCopyright © 2010 connectBlue AB Page 26 of 345.4 Recommended M2 screwIf a double-row connector with threaded inserts or press-fit nuts are used, then recommended for mounting of modules is a ISO 7380 M2compatible screw. A suitable screw is the BN6404 from Bossard, , with TORX T6 head cap. See figure below.www.bossard.comParameter Value Unitd2 3.5 mmk max 1.3 mmt max 0.8 mmA 2.0 mmIf other type of screw is used please ensure that d2 is less than 3.8 mm otherwise components near the mounting holescan be damaged.5.5 Antenna issuesThe unit cannot be mounted arbitrary, because of the radio communication. The unit with an internal surface mounted antenna cannot bemounted in a metal enclosure. No metal casing or plastics using metal flakes should be used, avoid also metallic based paint or lacquer.Keep a minimum clearance of 10 mm between the antenna and the casing. Keep 10 mm free space from metal around the antenna. If ametal enclosure is required, one of the external antenna options has to be used. See section 3.2 for more information on the antennaoptions available.
