X7R Dielectric General Specifications X7R formulations are called “temperature stable” ceramics and fall into EIA Class II materials. X7R is the most popular of these intermediate dielectric constant materials. Its temperature variation of capacitance is within ±15% from -55°C to +125°C. This capacitance change is non-linear. Capacitance for X7R varies under the influence of electrical operating conditions such as voltage and frequency. X7R dielectric chip usage covers the broad spectrum of industrial applications where known changes in capacitance due to applied voltages are acceptable.

Pad designs are given below for the most common sizes of multilayer ceramic capacitors for both wave and reflow soldering. The basis of these designs is: • Pad width equal to component width. It is permissible to decrease this to as low as 85% of component width but it is not advisable to go below this. • Pad overlap 0.5mm beneath component. • Pad extension 0.5mm beyond components for reflow and 1.0mm for wave soldering.

This is less important for reflow soldering but sufficient space must be allowed to enable rework should it be required. The rate of preheat should not exceed 4°C/second to prevent thermal shock. A better maximum figure is about 2°C/second. For capacitors size 1206 and below, with a maximum thickness of 1.25mm, it is generally permissible to allow a temperature differential from preheat to soldering of 150°C. In all other cases this differential should not exceed 100°C. For further specific application or process advice, please consult AVX. ≥1.5mm (0.06) ≥1mm (0.04) ≥1mm (0.04) 42 Cleaning Care should be taken to ensure that the capacitors are thoroughly cleaned of flux residues especially the space beneath the capacitor. Such residues may otherwise become conductive and effectively offer a low resistance bypass to the capacitor. Ultrasonic cleaning is permissible, the recommended conditions being 8 Watts/litre at 20-45 kHz, with a process cycle of 2 minutes vapor rinse, 2 minutes immersion in the ultrasonic solvent bath and finally 2 minutes vapor rinse. Surface Mounting Guide MLC Chip Capacitors APPLICATION NOTES General Good solderability is maintained for at least twelve months, provided the components are stored in their “as received” packaging at less than 40°C and 70% RH. Surface mounting chip multilayer ceramic capacitors are designed for soldering to printed circuit boards or other substrates. The construction of the components is such that they will withstand the time/temperature profiles used in both wave and reflow soldering methods. Solderability Handling Terminations to be well soldered after immersion in a 60/40 tin/lead solder bath at 235 ±5°C for 2±1 seconds. Chip multilayer ceramic capacitors should be handled with care to avoid damage or contamination from perspiration and skin oils. The use of tweezers or vacuum pick ups is strongly recommended for individual components. Bulk handling should ensure that abrasion and mechanical shock are minimized. Taped and reeled components provides the ideal medium for direct presentation to the placement machine. Any mechanical shock should be minimized during handling chip multilayer ceramic capacitors. Storage Leaching Terminations will resist leaching for at least the immersion times and conditions shown below. Termination Type Nickel Barrier Solder Solder Tin/Lead/Silver Temp. °C 60/40/0 260±5 Immersion Time Seconds 30±1 Preheat Recommended Soldering Profiles Reflow 300 Natural Cooling Preheat Solder Temp. 250 200 220°C to 250°C 150 Soldering 100 50 0 1min 10 sec. max 1min (Minimize soldering time) Wave Preheat Natural Cooling 250 Solder Temp. Mildly activated rosin fluxes are preferred. The minimum amount of solder to give a good joint should be used. Excessive solder can lead to damage from the stresses caused by the difference in coefficients of expansion between solder, chip and substrate. AVX terminations are suitable for all wave and reflow soldering systems. If hand soldering cannot be avoided, the preferred technique is the utilization of hot air soldering tools. Cooling 300 200 It is important to avoid the possibility of thermal shock during soldering and carefully controlled preheat is therefore required. The rate of preheat should not exceed 4°C/second and a target figure 2°C/second is recommended. Although an 80°C to 120°C temperature differential is preferred, recent developments allow a temperature differential between the component surface and the soldering temperature of 150°C (Maximum) for capacitors of 1210 size and below with a maximum thickness of 1.25mm. The user is cautioned that the risk of thermal shock increases as chip size or temperature differential increases. T 230°C to 250°C 150 100 50 0 1 to 2 min 3 sec. max (Preheat chips before soldering) T/maximum 150°C Natural cooling in air is preferred, as this minimizes stresses within the soldered joint. When forced air cooling is used, cooling rate should not exceed 4°C/second. Quenching is not recommended but if used, maximum temperature differentials should be observed according to the preheat conditions above. Cleaning Flux residues may be hygroscopic or acidic and must be removed. AVX MLC capacitors are acceptable for use with all of the solvents described in the specifications MIL-STD202 and EIA-RS-198. Alcohol based solvents are acceptable and properly controlled water cleaning systems are also acceptable. Many other solvents have been proven successful, and most solvents that are acceptable to other components on circuit assemblies are equally acceptable for use with ceramic capacitors. 43 Packaging of Chip Components Automatic Insertion Packaging TAPE & REEL QUANTITIES All tape and reel specifications are in compliance with RS481. 8mm Paper or Embossed Carrier (1) 12mm 0805, 1005, 1206, 1210 Embossed Only 0504, 0907 Paper Only 0402, 0603 1505, 1805, 1808 1812, 1825 2220, 2225 Qty. per Reel/7" Reel 2,000 or 4,000 (1) 3,000 1,000 Qty. per Reel/13" Reel 10,000 10,000 4,000 Dependent on chip thickness.

The clearance between the ends of the terminals or body of the component to the sides and depth of the cavity (A0, B0, and T) must be within 0.05 mm (.002) min. and 0.50 mm (.020) max. The clearance allowed must also prevent rotation of the component within the cavity of not more than 20 degrees (see sketches A & B). 2. Tape with components shall pass around radius “R” without damage. 3. 1.1 mm (.043) Base Tape and 1.6 mm (.063) Max. for Non-Paper Base Compositions.
