微型

tiny
🔬 微型 = 微 (micro/tiny) + 型 (type/model) → a micro-type, i.e. miniature
微 is the same 微 as in 微信 (WeChat) and 微波 (microwave) — it always means tiny or micro. 型 means type or model, as in 型号. Together: a tiny-scale model, hence miniature or micro-.
型 — earth 土 + 刑 (xíng, phonetic)
型 is a semantic-phonetic compound. The 土 (earth) component points to its original meaning: a clay or earthen mold used for casting. The right side 刑 supplies the sound. From 'casting mold' it broadened to mean 'model, type, pattern' in modern usage.
