1. Lumikizani mapepalawo ku mabowo. M'malo mwake, mawaya apakati pa zoyikapo ndi mabowo ayenera kugulitsidwa. Kupanda chigoba cha solder kumabweretsa zovuta zowotcherera monga malata ochepa olowa m'malo olumikizirana, kuwotcherera kozizira, mabwalo afupiafupi, zolumikizira zopanda unsolder, ndi miyala yam'manda.

2. Mapangidwe a chigoba cha solder pakati pa mapepala ndi mawonekedwe a solder mask pattern ayenera kugwirizana ndi mapangidwe a solder terminal yogawa magawo enieni: ngati kukana kwazenera kwa solder kumagwiritsidwa ntchito pakati pa mapepala, kukana kwa solder kumayambitsa solder. pakati pa mapepala pa nthawi ya soldering. Pakafupikafupi, mapadi amapangidwa kuti azikhala ndi zotsutsana zodziyimira pawokha pakati pa zikhomo, kotero sipadzakhala gawo lalifupi pakati pa ma pads panthawi yowotcherera.

3. Kukula kwa solder mask chitsanzo cha zigawo zikuluzikulu si koyenera. Mapangidwe a chigoba cha solder chomwe chili chachikulu kwambiri "chitetezana" wina ndi mnzake, zomwe zimapangitsa kuti pasakhale chigoba cha solder, ndipo kusiyana pakati pa zigawo zake kumakhala kochepa kwambiri.

4. Pali kudzera mabowo pansi pa zigawo popanda solder chigoba, ndipo palibe solder chigoba kudzera mabowo pansi pa zigawo zikuluzikulu. The solder pa kudzera mabowo pambuyo funde soldering zingakhudze kudalirika kwa IC kuwotcherera, ndipo angayambitsenso dera lalifupi la zigawo zikuluzikulu, etc.
