NOTE: Caution of hot wind from the reflow hole.

Removal of the solder fron the CSP installation area 
using soldering iron and desolder braid.
Be sure use less than 30W soldering iron.

Visually check for remaining solder using a magnifier.

Rainforced

Be careful not to produce soldering defects 
such as whisker or soldering inconsistency 
on the electrode lands.

NOTE: When using the desolder braid, be careful 

not to remove the land copper foil.

Reference: Some types of CSPs have reinforced 

lands and others not.

Wipe out the flux from the board surface using alcohol or others.

(*1: HOZAN Z-293, Code No. 92923 Flux remover)

Apply the flux lightly with a brush.

It is recommended to use a magnifier. (HOZAN L-55 + L-65 etc.)

Align the CSP with the alignment marks on the board. (Refer to "Installation area figure. A")
POINT: When viewed from above, the alignment marks should be visible along the CSP on the PCB.

After the CSP has been aligned, move the PCB to the SPOT HEATER / BOARD WARMER. 
Be careful not to vibrate the PCB while moving it.
After moving the PCB, check if the CSP does not deviate from the installation position using a magnifier 
or something.
