IPD Capacitor Assembly Set Up
Rev 1.0
Application Note
Outline
Silicon Capacitor for surface mounting device (SMD) assembly is a Wafer Level Chip Scale Packaging
with the following features:
Package dedicated to solve tombstoning effect of small SMD package;
Package compatible with SMD assembly;
Package without underfilling step;
Interconnect available with various optional finishing for specific assembly.
Assembly consideration
Standard pick & place equipment dedicated to WLCSP down to 400µm pitch.
Solder paste type 3 in most cases of EIA size.
Reflow has to be done with standard lead-free profile (for SAC alloys) or
according to JEDEC recommendations J-STD 020D-01.

Process recommendation
After soldering, no solder paste should touch the side of the capacitor die as that might results in
leakage currents due to remaining flux.
In order to use IPDiA standard capacitors within the JEDEC format and recommendation, the solder
flux must be cleaned after reflow soldering step.
Notes: for a proper flux cleaning process, “rosin” flux type (R) or “water soluble” flux type (WS) is
recommended for the solder printing material. “No clean” flux (NC) solder paste is not recommended.
In case the flux is not cleaned after the reflow soldering, the standard JEDEC would probably not be
appropriate and the solder volume must be controlled:
- using smallest aperture design for the stencil, and using finer solder paste type 4 or 5 for a
proper printing process.
- Mirroring pads would be the best recommendation
Application Note
Pad recommendation
The capacitor is compatible with generic requirements for flip chip design (IPC7094).
Standard IPDiA 3D package can be compliant with established EIA size (0201, 0402, 0603, …).
Die size and land pattern dimensions is set up according to following range :

Application Note
Manual Handling Considerations
These capacitors are designed to be mounted with a standard SMT line, using solder printing step,
pick and place machine and a final reflow soldering step. In case of manual handling and mounting
conditions, please follow below recommendations:
Minimize mechanical pressure on the capacitors (use of a vacuum nozzle is
recommended).
Use of organic tip instead of metal tip for the nozzle.
Minimize temperature shocks (Substrate pre-heating is recommended).
No wire bonding on 0402 47nF, 0402 100nF, 1206 1 F and 1812 3,3µF
Process steps:
On substrate, form the solder meniscus on each land pattern targeting 100 µm
height after reflow (screen printing, dispensing solder paste or by wire soldering).
Pick the capacitor from the tape & reel or the Gel Pack keeping backside visible
using a vacuum nozzle and organic tip.
Temporary place the capacitor on land pattern assuming the solder paste (Flux)
will stick and maintain the capacitor.
Reflow the assembly module with a dedicated thermal profile (see reflow
recommendation profile).
