RF-35 radio frequency Taconic pcb with immersion Tin surface finishing

 

The advantages of Immersion Tin

● Excellent flatness

● Mid range cost for lead free finish

● Good for fine pitch / BGA / smaller components

● Top choice for press fit technology

● Reworkable

The disadvantages of Immersion Tin

● Very sensitive to handling – gloves must be used

● Exposed Tin on final assembly can corrode

● Not good for multiple reflow/assembly processes

● Aggressive to soldermask – soldermask dam should be more than 5mil
● Baking prior to use can have a negative effect
