- Recommended soldering conditions for refl ow For soldering (Example : Sn/Pb) For lead-free soldering (Example : Sn/Ag/Cu)
- Recommended soldering conditions for fl ow In case of fl ow soldering, the land width must be small er than the Chip Resistor width to properly control the sol der amount properly. Generally, the land width should be 0.7 to 0.8 times (W) of the width of chip resistor. In case of refl ow soldering, solder amount can be adjusted, there fore the land width should be set to 1.0 to 1.3 times chip resistor width (W). ■ Recommended Land Pattern Safety Precautions The following ar e precautions for individual products. Please also refer to the precautions common to Fixed Resistors shown on page ER2 of this catalog. 1. Keep th e rated power and ambient temperature within the specifi ed derating curve. * When positioning an d mounting Metal Film Chip Resistors (hereafter called the resistors), make allowance for the effect of heat generated through close contact between the resistors and neigh bor ing components and for the temperature rise of adjacent heat-generating components. 2. If a transien t load (heavy load in a short time) like a pulse is expected to be applied, check and evaluate the operations of the resistors when installed in your products before use. When applying pulses to the resistors, keep the pulse peak within the rated voltage. 3. Do not us e halogen-based or other high-activity fl ux. Otherwise, the residue may impair the resistors' per for mance and/or reliability. 4. When soldering with a soldering iron, never touch the resist ors' bodies with the tip of th e soldering iron. When using a soldering iron with a high temperature tip, fi nish soldering as quickly as possible (within three seconds at 350 °C max.). 5. As the amount of applied solder becomes larger, the me chanical stress applied to the resistors increases, causing problems such as cracks and faulty characteristics. Avoid applying an excessive amount of solder. 6. When the resistor s' protective coat ings are chipped, fl awed, or removed, th e characteristics of the resistors may be impaired. Take special care not to apply mechanical shock during automatic mounting or cause damage during handling of the boards with the resistors mounted. 7. Do not appl y shock to the resistors or pinch them with a hard tool (e.g. pliers and tweezers). Otherwise, the resistors' protective coatings and bodies may be chipped, affecting their performance. 8. Avoid excessive bending of printed circuit boards in order to protect the resistors from abnormal stress. 9. Do no t immerse the resistors in solvent for a long time. Before using solvent, carefully check the effects of im mer sion.
- Refl ow soldering shall be performed a maximum of two times.
- Please contact us for additional information when used in conditions other than those specifi ed.
- Please meas ure the temperature of the terminals and study every kind of solder and printed circuit board for solderability be fore ac tu al use. Feb. 2009
– ER3 – Safety Precautions (Common precautions for Fixed Resistors) When using ou r products, no matter what sort of equipment they might be used for, be sure to make a written agreement on the specifi cations with us in advance. The design and specifi cations in this catalog are subject to change without prior notice. Do not use the products beyond the specifi cations described in this catalog. This cata log explains the quality and performance of the products as individual components. Be fore use, check and evaluate their operations when installed in your products. Install the following systems for a failsafe design to ensure safety if these products are to be used in equip ment where a defect in these products may cause th e loss of human life or other signifi cant damage, such as damage to vehicles (au to mo bile, train, vessel), traffi c lights, medical equipment, aerospace equipment, elec tric heating ap pli anc es, com bus tion/gas equipment, rotating equipment, and disaster/crime prevention equip ment. ✽ Systems equipped with a protection circuit and a protection device ✽ Systems equipped with a redundant circuit or other system to prevent an unsafe status in the event of a single fault (1) Precautions for use These products are designed and manufactured for general and stan dard use in general elec tron ic equipment (e.g. AV equipm ent, home el ectric ap pli anc es, offi ce equipment, information and com mu ni ca tion equipment) These products are not intended fo r use in the following special conditions. Be fore using the products, care ful ly check the effects on their quality and performance, and determine whether or not they can be used. 1. In liquid, such as water, oil, chemicals, or organic solvent 2. In direct sunlight, outdoors, or in dust 3. In salty air or air with a high concentration of corrosive gas, such as Cl 2, H2S, NH3, SO2, or NO2 4. Electric Static Discharge (ESD) Environment These components are sensitive to static electricity and can be damaged under static shock (ESD). Please take measures to avoid any of these environments. Smaller components are more sensitive to ESD environment. 5. Electromagnetic Environment Avoid any environment where strong electromagnetic waves exist. 6. In an environment where these pr oducts cause dew condensation 7. Sealing or co ating of these products or a printed circuit board on which thes e products are mounted, with resin or other materials These products generate Joule heat when energized. Carefu lly position th ese products so that their he at will not affect the other components. Carefully position thes e products so that their temperatures will not exceed the category temperature range due to the effect s of neighboring heat-generating com po nents. Do not mount or place heat-generating com po nents or infl ammables, such as vinyl-coated wires, near these products . Note that non- cleaning solder, halogen-based highly active fl ux, or wate r-soluble fl ux may dete riorate the performance or reliability of the products. Carefully select a fl ux cleaning agent fo r use after soldering. An unsuit able agent may deteriorate the performance or reliability. In particular, when using water or a water-soluble cleaning agent, be careful not to leave water res i dues. Otherwise, the insulation performance may be deteriorated. (2) Precautions for storage The performance of these products, including the solderability, is guar anteed for a year from the date of arrival at your company, provided that they remain packed as they were wh en delivered and stored at a temperature of 5 °C to 35 ° C and a relative humidity of 45 % to 85 %. Even wi thin the above guarantee periods, do not store these products in the fol low ing conditions. Otherwise, their elec tri cal performance and/or solderability may be dete riorated, and the packaging materials (e.g. tap ing ma te ri als) may be de formed or deteriorated, resulting in mounting failures. 1. In salty air or in air with a high concentration of corrosive gas, such as Cl 2, H2S, NH3, SO2, or NO2 2. In direct sunlight <Package markings> Package markings include the product number, quantity, and country of origin. In principle, the country of origin should be indicated in English. Oct. 2007
