45 Notice of Chip Coil 2. Mounting Instructions Land Pattern Dimensions Large lands reduce Q of the mounted chip. Also, large protruding land areas (bordered by lines having dimensions c and d shown below) cause floating and electrode cracks. 4Amount of Solder Paste Excessive solder causes electrode corrosion, while insufficient solder causes low electrode bonding strength. Adjust the amount of solder paste so that solder is applied as shown below. Land Solder Resist c LQH/LQN LQS d 2Magnetic Coupling Since some chip coils are constructed like an open magnetic circuit, narrow spacing between coils may cause magnetic coupling. (Please refer to Page 54 for coil-to-coil spacing and coupling coefficient.) The LQS and LQG series have a magnetically shielded structure. The structure makes their coupling coefficient smaller than that of conventional chip coils. In particular, the LQS33N series has a very small coupling coefficient.

In contrast, if insufficient adhesive is applied, or if the adhesive is not sufficiently hardened, then the chip may become detached during flow soldering. Apply the adhesive in accordance with the following conditions. 3PCB Warping Arrange chip coils to minimize stress caused by PCB warping.

46 Notice of Chip Coil 3. Standard Soldering Conditions Soldering Method Chip coils can be flow or reflow soldered. (LQS33N, LQS66C and LQPA should only be reflow soldered) Please contact Murata regarding other soldering methods. The volume of solder can cause minor fluctuations in inductance value. Therefore, carefully control the amount of solder when soldering the LQPA/A, LQGA/A and LQW608A series. 2Soldering Temperature and Time Solder within the temperature and time combinations indicated by the slanted lines in the following graphs. If soldering is repeated, please note that the allowed time is the accumulated time. 4Standard Soldering Conditions Flow Solder Temperature (D) 0 0 Pre-heating (in air) minute min. 3 sec. max.

47 Notice of Chip Coil 4. Cleaning The following conditions should be observed when cleaning chip coils. Cleaning Temperature : 60D max. (40D max. for CFC alternatives and alcohol cleaning agents) 2Ultrasonic Output : W/R max. Duration : 5 minutes max. : 28 to 40kHz Care should be taken not to cause resonance of the PCB and mounted products. 3Cleaning Agent The following cleaning agents have been tested on individual components. Evaluation in complete assembly should be done prior to production. a) CFC alternatives and alcohol cleaning agents #Isopropyl alcohol (IPA) #HCFC-225 b) Aqueous cleaning agents #Surface active agent (Clean Thru 750H) #High grade alcohol (Pine Alpha ST-S) #Hydrocarbon (Techno Cleaner 335) #Alkaline saponifier (Aqua Cleaner 240-cleaner should be diluted to % using deionized water.) LQS series : Aqueous agents should not be used because they may cause quality deterioration. LQH series : Surface active agent and high grade alcohol can be used. 4Ensure that flux residue is completely removed. Component should be thoroughly dried after aqueous agents have been removed with deionized water. For additional cleaning methods, please contact Murata. 5. Resin Coating When coating products with resin, the relatively high resin curing stress may change inductance values. For exterior coating, select resin carefully so that electrical and mechanical performance of the product is not affected. 6. Caution for Use This item is designed to have sufficient strength, but handle with care not to make it chipped or broken due to its ceramic structure. LQW Series # Sharp material, such as a pair of tweezers, shall not touch to the winding portion to prevent the breaking of wire. # Do not give excessive mechanical shock to the products mounted on the board to prevent the breaking of the core. # In some mounting machines, when picking up components support pin pushes up the components from the bottom of base tape. In this case, please remove the support pin. The support pin may damage the components and break wire. LQH/LQN Series # Sharp material, such as a pair of tweezers, shall not touch to the winding portion to prevent the breaking of wire. # Do not give excessive mechanical shock to the products mounted on the board to prevent the breaking of the core. LQP Series # The pattern of the chip coil is covered with the protection film. But the handling the chip coil shall be taken care so that the chip coil would not be damaged with the pick-up nozzle, the sharp substance and so on. LQG-N/-C/-F Series # There is possibility that the inductance value change due to magnetism. Don't use a magnet or a pair of tweezers with magnetism when chip coil are handled. (The tip of the tweezers should be molded with resin or pottery.) 7. Handling Avoid applying excessive stress to products to prevent damage. 2Do not touch winding with sharp objects such as tweezers to prevent wire breakage. 3Do not apply excessive force to products mounted on boards to prevent core breakage. 8. Operating Environment Do not use products in corrosive gases atmosphere such as chlorine gas, acid or sulfide gas. 9. Storage Requirements Storage Period Products should be used within 2 months reckon from the date of our out-going inspection. Solderability should be verified if this period is exceeded. (LQS33N/33C, LQP2A series should be used within 6 months.) 2Storage conditions a) Store products in a warehouse in compliance with the following conditions : Temperature : Y to 40D Humidity : 30 to 70% (relative humidity) Do not subject products to rapid changes in temperature and humidity. Do not store them in corrosive gases atmosphere such as one containing sulfurous acid gas or alkaline gas. This will prevent electrode oxidation which causes poor solderability and possible corrosion of coils. b) Do not store products in bulk packaging to prevent collision among coils which causes core chipping and wire breakage. c) Store products on pallets to protect from humidity, dust, etc. d) Avoid heat shock, vibration, direct sunlight, etc.. Transportations Do not apply excessive vibration or mechanical shock to products. 45
