(1) After switches were soldered, please be careful not to clean switches with solvent
After the switch is dip-soldered, be careful not to clean it with solvent.
(2) In the case of using soldering iron, soldering conditions shall be 350ºC max and 3 sec. max
In the case of using ferrochrome, the solder temperature should be below 350°C, within 3 seconds.
(3) Right after switches were soldered; please be careful not to load on the knobs of switches.
After dip welding, be careful not to apply a load on the top.
3. 2 Design instructions(Matters needing attention in design)
(1) Follow recommended P. W. B. piercing plan in outside drawing page. Refer to the product drawing for the mounting hole size of the printed substrate.
(2) Design key top as fig. Design inclination of key top 4 deg. max as fig. (Recommended operating condition.)
The keystroke design is shown in the figure, and the keystroke inclination is within 4 degrees. (See operating conditions).
3.3 Note(Attention point)
(1) Please be cautious not to give excessive static load or shock to switches.
Be careful not to apply excessive pressure or shake the switch.
(2) Please be careful not to pile up P. W. B. after switches were soldered.
After the switch is soldered, be careful not to stack the printed substrates.
(3) Preservation under high temperature and high humidity or corrosive gas should be avoided
especially. When you need to preserve for a long period, do not open the carton.
In particular, care should be taken to avoid high humidity and high temperature and corrosive gas environment. If you need to store for a long time, please do not open the box.
3.4 Note(AttentionPoint)
Due to the possibility of modification and change of products, customers should check or trial production in small batches after receiving the goods, and batch production can only be carried out after confirmation.
