Reflow palette
made from Magnesium
alloy AZ61
|
In recent
years, a reflow soldering is becoming a main method along with miniaturizing
and high precision accuracy of parts in mounting electronic parts on the PCBs
(Printed Circuit Boards). For obtaining the protection of electronic parts and
the productivity improvement, the importance of the reflow palette used in the
reflow furnace is increasing and the reflow palette made from Magnesium AZ61
has the most suitable features stated as follows;

●Excellent merits in the reflow palette made from AZ61
| 1. |
For
improving the workability
|
| |
The productivity improvement can be obtained by improving the workability
because magnesium is the lightest in all the commonly used metals (specific
gravity of AZ61: 1.8). |
| 2. |
Easy control on the
temperature |
| |
Because magnesium alloy has a little specific
heat and good heat reaction against the temperature change in the furnace, it
is possible to obtain the correct temperature adjustment. |
| 3. |
Good in durability |
| |
The palette made from AZ61 has
longer life than the palettes made from other metals or resins because the
strain against the temperature of magnesium alloy is very little and has an
excellent dimensional stability.
|
| 4. |
Achievement of total
reduction in costs |
| |
The total reduction in costs can be achieved by above items 1 ~ 3. |
●Very good balance at magnesium alloy AZ61
| Though many other magnesium alloys also fit for the reflow palette, AZ61 is especially the best material. Because AZ61 has both weight-to-strength ratio and corrosion resistance, more over is very good at formability and machinability. The sheet of 1 – 3 mm in thickness is generally used. |
