Chapter 2: How to Build a Chip Component (CC)

Chip Components (CC) are leadless packages which include resistors, ceramic capacitors, ferrite beads, and diodes.

A- Capacitor • B- Diode • C- LED • D- Inductor • E- Thermistor • F- Capacitor

Note: There are special considerations for resistor networks or capacitor arrays. See the section below Resistor Networks and Capacitor Arrays.

ID Tab

Part Type: Refer to the part data sheet. Typical Part Type for the CC include CAPACITOR CERAMIC, RESISTOR, FERRITE BEAD, and DIODE (for LEDs).
Failure Class: This can be left blank. The property is not used in any Sherlock stand-alone analysis. It is only used when Sherlock is part of a multi-tool analysis workflow.

Chip Component Properties:

2.1. CC Package Properties

Package Tab

Package Name: Refer to the part data sheet. Example: 0402.
Package Type: CC
Package Mount: SMT

Package Length: Refer to the part data sheet. If not listed, use the default package dimension in the table below.

Tip: Always give priority to the part data sheet. However, if the dimensions are not listed, use the default dimensions from the table below. The CC package name is an industry standard numeric code based on part dimensions. Cross reference the part code with its default dimensions.

2512	6332	0.25	6.3	0.12	3.2	0.024	0.6	1

Package Width: Refer to the part data sheet. If not listed, use the default dimension in the table above.
Package Thickness: Refer to the part data sheet. If not listed, use the default height dimensions in the table above.
Model Part: ENABLED
Corner Shape: Typically, SQUARE.
A = Square Corner • B = Miter Corner • C = Round Corner • Arrows show corner radius.
Corner Radius: For SQUARE, radius does not apply. See image above for MITER and ROUND corners.
Corner Face: Typically, TOP_BOTTOM.
D = TOP_BOTTOM • E = FRONT_BACK • F = LEFT_RIGHT
Material: Refer to the part data sheet. If the material is not listed, use the following guidelines.
- Ceramic Capacitors: Material is based off the dielectric. If dielectric is C0G or NP0, then enter CALCIUM ZIRCONATE. Otherwise the material is typically BARIUMTITANATE.
- Resistors: Material is typically ALUMINA unless data sheet states otherwise.
- Ferrite Beads: Material is typically FERRITE unless the data sheet states otherwise.
- Diodes: Material is typically ALUMINA unless the data sheet states otherwise.
Junction Res (C/W): This can be left blank. The property is not used in any Sherlock stand-alone analysis. It is only used when Sherlock is part of a multi-tool analysis workflow.

2.2. CC Lead Properties

Lead Tab

Lead Count: Refer to the part data sheet. In the case of CC's, Lead Count refers to the number terminations soldered to the board.
Lead Geometry: LEADLESS

2.3. CC Pad Properties

Pad Tab

PCB artwork, when available, supercedes pad dimensions given by a data sheet or a standard.

Tip: If you have a completed Sherlock model, use the Update Pad Properties Tool in Sherlock which is designed to automate entering pad properties.

This table shows recommended pad dimensions for CC Resistor, Inductor, and Capacitor parts. It is included for reference. PCB artwork should be used as the input!
CC Component	Length	Width	Pad Length	Pad Width	Pitch
01005	0.4	0.2	0.18	0.2	0.3
0201	0.6	0.3	0.3	0.3	0.6
0306	0.8	1.6	0.5	1.6	0.8
0402	1	0.5	0.5	0.5	1

2512	6.4	3.2	2	3.2	6.4

2.4. CC Solder Properties

Solder Tab

Solder Material: Typically, DEFAULT
When set to DEFAULT, Sherlock uses the Default Solder Type specified in the Circuit Card Properties. To view or edit these properties, right-click the circuit card in the Project Tree and select Circuit Card Properties in the context menu.
If a solder other than the default is used for this part, you may enter the name of the solder in the Solder Material field. To add a custom solder to the Solder Library, see Solder Management in the Sherlock User's Guide.
Solder Model: CC MODEL. This model is valid for all Ceramic Chips.
Solder Thickness: Sherlock calculates this value. It is based on the stencil thickness as recorded in the Circuit Card Properties and is assumed to be half that value.
To view or edit Circuit Card Properties, right-click the circuit card in the Project Tree and select Circuit Card Properties in the context menu.

2.5. Resistor Networks and Capacitor Arrays

There are variations of CC resistors and capacitors that combine multiple devices into a single SMT package. They are often called arrays or networks.

A = Resistor Network • B = Capacitor Array

In Sherlock, these are defined in a manner similar to how standard two-lead CC resistors and capacitors are defined. The main difference is seen when the number of leads increases. A four-element capacitor array, for example, has eight leads. You would still use the package dimensions provided by the datasheet, and you would follow the standard assumptions used for CC resistors and capacitors—such as assigning materials when that information is not provided by the manufacturer.
