How to get the Profile

Thermal profile is gotten from the data logger

1.Puting the board profile on the machine carrier

2.plug the thermocouple to thermal profiler

3.Open the reflow program(doing via the SRT solfware 1-2-3-go)

4.Completed cycle then loading the graph from thermal profiler

5.Analyse that profile graph if it cannot achive the target ,parameter need to adjust.

Machine for reworking BGA

The rework machine that use for removing and replacing BGA and SMD components it have many type and many manufacture.According from the picture is SRT machine that simplify to use,It can be set profile by using the graphic on its software.I 'm showing the sample graph profile from the SRT machine .This machine very useful for SMD reworking and less downtime from machine error or machine breakdown.

It also can be used with Pb-Free Solder.

BGA REWORK

BGA Reworking process that need to get the thermal profile before remove or replace .The solution for getting thermal profile that it need be selected the location to put the thermocouple, normally all bga must read the thermal profile 4 point at the edge 2 point ,center 1 point and its lid 1 point
