Short Quiz

Batch Process

A process that builds 70% of the MLCC. It is a process of mixing solvent, binder, and ceramic powder

Solvent
Binder Resin
Ceramic Powder (BT Powder)

what are the component to make up batch process

Binder Solution
Additive Solution

Two job material for slurry

Active
Cover
Gap

3 Main Output of Slurry

Active

Cover

Gap

_____ A output where electrode is printed “upon casting”

_____ A output where electrode is not printed and is place on top and bottom part of the chip

______A output that act as a “margin” and is only for 6th Generation

Weighing & Pre mixing

Raw material is weigh, solvent and dispersant is being mix

Milling

A process where powdered particle are being dispers uniformly

Centrifugation

A process that include centrifugal force to separate particle

Microfluidizer

A process where slurry us subjectto high pressure

Filtering

A process which a purpose is to remove any foreign matter & agglomerated particle

Aging

A process of removing bubble fromthe mixture

Normal = 2 hours

4 Models from batch process

Normal = 300nm above
Weighing & Premixing → Initial Milling → Final Milling → Aging

High End = 300 nm below
Weighing & Premixing → Initial filtering → Binder Input → Initial Microfluidizer
→ Additive Input → Final Premixing → Final Filter → Aging

High End 2 =
Weighing & Premixing → Initial filtering → Additive Input → Final Microfluidizer → Final Premixing → Final filtering → Aging

03A105 & 05A186
Weighing & Premixing → Initial filtering → Centrifugation → Binder Input → Initial Microfluidizer → Additive Input → Final Premixing → Final Filter → Aging

7 Raw material for Slurry

Dispersant

A surfactant (deflocculant) subtance that allow the particle to separate for the binder can distribute uniformly around the particles.

BYK - 103
RE - 610

2 types of Dispersant

Plasticizer

acts like a lubricant between polymer chains. It gives the chains more freedom to move, making the material softer, more flexible, and less likely to crack or break under stress.

Mineral Spirit

A process to reduce the membrane thickness or reduce the viscosity of the casting solution. Also a process to obtain lower sheet density

Polyviynl Butyral

meaning of PVB

Acetal
Acetyle
Hydroxyl

PVB groups

Binder Composition

A total resin content with respect to powder quantity and plasticizer with respect to binder

Viscosity
Density
Solid Rate
BET
XRF
Mole Ratio

Commong Inspection Process for Batch Process

Viscosity

A MPQA process that measure the resistance the gradual deformation of the slurry

Thixotropic

What kind of behavior does Batch process slurry has?

Density

substance mass is divided by volume

Solid Rate

to check for any solid matter that the mixture contain

Microfluidizer

A process of machine that use high pressure pump to enable the fluid to pass through micro

BET (Braunauer Emmett Teller)

This measure specific surface area of final division and pores through adsorption

Deaeration Process
Adsorption Process
Desorption Process

3 BET Analysis

deaeration process

A BET analysis to remove impurities

Adsorption Process

A BET analysis where glass cell is subjected to liquid nitrogen for rapid cooling

Desorption

A BET analysis where glass cell is remove from liquid nitrogen

X-RAY Fluorescent

A MPQA Process to measure the element intensity or thickness

Mole ratio

A MPQA Process that measures Ba-Ti mole using XRF spectroscopy
