2. Surface-mount technology - Wikipedia

   en.wikipedia.org/wiki/Surface-mount_technology

   SMD (non-electrolytic) capacitors, which are usually monolithic ceramic capacitors, exhibit the same body color on all four faces not covered by the end caps. SMD electrolytic capacitors, usually tantalum capacitors, and film capacitors are marked like resistors, with two significant figures and a multiplier in units of picofarads or pF, (10 ...

   SMD capacitors (on the left) with two through-hole capacitors (on the right) Main article: Chip carrier Surface-mount components are usually smaller than their counterparts with leads, and are designed to be handled by machines rather than by humans.

4. Solder paste - Wikipedia

   en.wikipedia.org/wiki/Solder_paste

   Solder paste is used in the manufacture of printed circuit boards to connect surface mount components to pads on the board. It is also possible to solder through-hole pin in paste components by printing solder paste in and over the holes. The sticky paste temporarily holds components in place; the board is then heated, melting the paste and ...

5. Metal electrode leadless face - Wikipedia

   en.wikipedia.org/wiki/Metal_electrode_leadless_face

   During automated SMT pick-and-place, this happens mostly if the mechanical pressure of the SMD placer nozzle is too low. If the MELF components are placed into the solder paste with enough pressure, then this problem can be minimized. Care must be taken with glass diodes which are less mechanically robust than resistors and other MELF components.

6. Ceramic capacitor - Wikipedia

   en.wikipedia.org/wiki/Ceramic_capacitor

   Ceramic capacitors may experience changes to their electrical parameters due to soldering stress. The heat of the solder bath, especially for SMD styles, can cause changes of contact resistance between terminals and electrodes. For ferroelectric class 2 ceramic capacitors, the soldering temperature is above the Curie point. The polarized ...

7. Through-hole technology - Wikipedia

   en.wikipedia.org/wiki/Through-hole_technology

   Through-hole (leaded) resistors. In electronics, through-hole technology (also spelled "thru-hole") is a manufacturing scheme in which leads on the components are inserted through holes drilled in printed circuit boards (PCB) and soldered to pads on the opposite side, either by manual assembly (hand placement) or by the use of automated insertion mount machines.
