A detailed application note is available at syfer.com Syfer recommend hot air/gas as the preferred method of applying heat for rework. Apply even heat surrounding the component to minimise internal thermal gradients. Soldering irons or other techniques that apply direct heat to the chip or surrounding area should not be used as these can result in micro cracks being generated. Reflow Soldering Syfer recommend reflow soldering as the preferred method for mounting MLCCs. Syfer MLCCs can be reflow soldered using a reflow profile generally defined in IPC/FEDEC J-STD-020. Sn plated termination chip capacitors are compatible with both conventional and lead free soldering with peak temperatures of 260 to 270C acceptable. The heating ramp rate should be such that components see a temperature rise of 1.5 to 4C per second to maintain temperature uniformity through the MLCC. The time for which the solder is molten should be maintained at a minimum, so as to prevent solder leaching. Extended times above 230C can cause problems with oxidation of Sn plating. Use of an inert atmosphere can help if this problem is encountered. Palladium/Silver (Pd/Ag) terminations can be particularly susceptible to leaching with free lead, tin rich solders and trials are recommended for this combination. Cooling to ambient temperature should be allowed to occur naturally, particularly if larger chip sizes are being soldered. Natural cooling allows a gradual relaxation of thermal mismatch stresses in the solder joints. Forced cooling should be avoided as this can induce thermal breakage. Wave Soldering Wave soldering is generally acceptable, but the thermal stresses caused by the wave have been shown to lead to potential problems with larger or thicker chips. Particular care should be taken when soldering SM chips larger than size 1210 and with a thickness greater than 1.0mm for this reason. Maximum permissible wave temperature is 270C for SM chips. The total immersion time in solder should be kept to a minimum. It is strongly recommended that Sn/Ni plated terminations are specified for wave soldering applications. Solder Leaching Leaching is the term for the dissolution of silver into the solder causing a failure of the termination system which causes increased ESR, tan and open circuit faults, including ultimately the possibility of the chip becoming detached. Leaching occurs more readily with higher temperature solders and solders with a high tin content. Pb free solders can be very prone to leaching certain termination systems. To prevent leaching, exercise care when choosing solder allows and minimize both maximum temperature and dwell time with the molten solder. Plated terminations with nickel or copper anti-leaching barrier layers are available in a range of top coat finishes to prevent leaching occurring. These finishes also include Syfer FlexiCapTM for improved stress resistance post soldering. Multilayer ceramic chip with nickel or copper barrier termination Minimise the rework heat duration and allow components to cool naturally after soldering. Use of Silver Loaded Epoxy Adhesives Chip capacitors can be mounted to circuit boards using silver loaded adhesive provided the termination material of the capacitor is selected to be compatible with the adhesive. This is normally PdAg. Standard tin finishes are often not recommended for use with silver loaded epoxies as there can be electrical and mechanical issues with the joint integrity due to material mismatch. Handling & Storage Components should never be handled with fingers; perspiration and skin oils can inhibit solderability and will aggravate cleaning. Chip capacitors should never be handled with metallic instruments. Metal tweezers should never be used as these can chip the product and leave abraded metal tracks on the product surface. Plastic or plastic coated metal types are readily available and recommended - these should be used with an absolute minimum of applied pressure. Incorrect storage can lead to problems for the user. Rapid tarnishing of the terminations, with an associated degradation of solderability, will occur if the product comes into contact with industrial gases such as sulphur dioxide and chlorine. Storage in free air, particularly moist or polluted air, can result in termination oxidation. Packaging should not be opened until the MLCs are required for use. If opened, the pack should be re-sealed as soon as practicable. Alternatively, the contents could be kept in a sealed container with an environmental control agent. Long term storage conditions, ideally, should be temperature controlled between -5 and +40C and humidity controlled between 40% and 60% R.H. Taped product should be stored out of direct sunlight, which might promote deterioration in tape or adhesive performance. Product, stored under the conditions recommended above, in its "as received" packaging, has a minimum shelf life of 2 years. SM Pad Design Syfer conventional 2-terminal chip capacitors can generally be mounted using pad designs in accordance with IPC-7351, Generic Requirements for Surface Mount Design and Land Pattern Standards, but there are some other factors that have been shown to reduce mechanical stress, such as reducing the pad width to less than the chip width. In addition, the position of the chip on the board should also be considered. 3-terminal components are not specifically covered by IPC7351, but recommended pad dimensions are included in the Syfer catalogue/website for these components.

Our answer is a proprietary flexible epoxy polymer termination material that is applied to the device under the usual nickel barrier finish. FlexiCapTM will accommodate a greater degree of board bending than conventional capacitors. Ranges are available with FlexiCapTM termination material offering increased reliability and superior mechanical performance (board flex and temperature cycling) when compared with standard termination materials. Refer to Syfer application note reference AN0001. FlexiCapTM capacitors enable the board to be bent almost twice as much as before mechanical cracking occurs. Refer to application note AN0002. FlexiCapTM is also suitable for space applications having passed thermal vacuum outgassing tests. Refer to Syfer application note reference AN0026. REACH (Registration, Evaluation, Authorisation and restriction of Chemicals) Statement The main purpose of REACH is to improve the protection of human health and the environment from the risks arising from the use of chemicals. Syfer Technology Ltd maintains both ISO 14001, Environmental Management System and OHSAS 18001 Health & Safety Management System approvals that require and ensure compliance with corresponding legislation such as REACH. For further information, please contact the sales office at SyferSales@knowles.com RoHS Compliance Syfer routinely monitors world wide material restrictions (e.g., EU/China and Korea RoHS mandates) and is actively involved in shaping future legislation. All standard C0G/NPO, X7R, X5R and High Q Syfer MLCC products are compliant with the EU RoHS directive (see below for special exemptions) and those with plated terminations are suitable for soldering common lead free solder alloys (refer to `Soldering Information' for more details on soldering limitations). Compliance with EU RoHS directive automatically signifies compliance with some other legislation (e.g., Korea RoHS). Please refer to the Sales Office for details of compliance with other materials legislation. Breakdown of material content, SGS analysis reports and tin whisker test results are available on request. Most Syfer MLCC components are available with non-RoHS compliant tin/lead (SnPb) Solderable termination finish for exempt applications and where pure tin is not acceptable. Other tin free termination finishes may also be available - please refer to the Sales Office for further details. X8R ranges <250Vdc are not RoHS 2011/65/EU compliant. Syfer has delivered millions of FlexiCapTM components and during that time has collected substantial test and reliability data, working in partnership with customers world wide, to eliminate mechanical cracking. An additional benefit of FlexiCapTM is that MLCCs can withstand temperature cycling from -55 to 125C in excess of 1,000 times without cracking. TM FlexiCap termination has no adverse effect on any electrical parameters, nor affects the operation of the MLCC in any way. Application Notes FlexiCapTM may be handled, stored and transported in the same manner as standard terminated capacitors. The requirements for mounting and soldering FlexiCapTM are the same as for standard SMD capacitors. For customers currently using standard terminated capacitors there should be requirement to change the assembly process when converting to FlexiCapTM. Based upon the board bend tests in accordance with IEC 60384-1 the amount of board bending required to mechanically crack a FlexiCapTM terminated capacitor is significantly increased compared with standard terminated capacitors. Product: X7R Typical bend performance under AEC-Q200 test conditions Standard Termination 2mm to 3mm FlexiCapTM 115Vac 400Hz ranges are not RoHS 2011/65/EU compliant. Check the website, www.knowlescapacitors.com/syfer for latest RoHS update. Export Controls and Dual-use Regulations Certain Syfer catalogue components are defined as `dual-use' items under international export controls - those that can be used for civil and military purposes which meet certain specified technical standards. The defining criteria for a dual-use component with respect to Syfer products is one with a voltage rating of >750V and a capacitance value >250nF and a series inductance <10nH. Components defined as `dual-use' under the above criteria automatically require a licence for export outside the EU, and may require a licence for export with the EU. The application for a licence is routine, but customers for these products will be asked to supply further information. Please refer to the sales office if you require any further information on export restrictions. Other special components may additionally need to comply with export regulations.

The crystalline structure for barium titanate based ceramics changes on passing through its Curie temperature (known as the Curie Point) at about 125C. The domain structure relaxes with time and in doing so, the dielectric constant reduces logarithmically; this is known as the ageing mechanism of the dielectric constant. The more stable dielectrics have the lowest ageing rates. One of the advantages of Syfer's unique `wet process' of manufacture is the ability to offer capacitors with exceptionally tight capacitance tolerances. The ageing process is reversible and repeatable. Whenever the capacitor is heated to a temperature above the Curie Point the ageing process starts again from zero. The ageing constant, or ageing rate, is defined as the percentage loss of capacitance due to the ageing process of the dielectric which occurs during a decade of time (a tenfold increase in age) and is expressed as percent per logarithmic decade of hours. As the law of decrease of capacitance is logarithmic, this means that for a capacitor with an ageing rate of 1% per decade of time, the capacitance will decrease at a rate of: The accuracy of the printing screens used in the fully automated, computer controlled manufacturing process allows for tolerance as close as 1% on C0G/NP0 parts greater than or equal to 10pF. For capacitance value less than 4.7pF tolerances can be as tight as 0.05pF. Periodic Tests Conducted and Reliability Data For standard surface mount capacitors components are randomly selected on a sample basis and the following routine tests conducted: Load Test. 1,000 hours @ 125C (150C for X8R). Applied voltage depends on components tested Humidity Test. 168 hours @ 85C/85%RH Board Deflection (bend test) a) 1% between 1 and 10 hours Test results are available on request. b) An additional 1% between the following 10 and 100 hours Conversion Factors c) An additional 1% between the following 100 and 1000 hours d) An additional 1% between the following 1000 and 10000 hours e) The ageing rate continues in this manner throughout the capacitor's life. Typical values of the ageing constant for our MLCCs are Dielectric Class Typical Values Ultra Stable C0G/NP0 Negligible capacitance loss through ageing Stable X7R <2% per decade of time From To Operation FITs MTBF (hours) 109 / FITs FITs MTBF (years) 109 / (FITs x 8760) FIT = Failures In Time. 1 FIT = 1 failure in 109 hours MTBF = Mean Time Between Failure Example of FIT Data Available Capacitance Measurements Because of ageing it is necessary to specify an age for reference measurements at which the capacitance shall be within the prescribed tolerance. This is fixed at 1000 hours, since for all practical purposes there is not much further loss of capacitance after this time. All capacitors shipped are within their specified tolerance at the standard reference age of 1000 hours after having cooled through their Curie temperature. The ageing curve for any ceramic dielectric is a straight line when plotted on semi-log paper.
