Synthetic Stone SMT Carrier (合成石SMT載具)

Synthetic Stone SMT Carrier (合成石SMT載具)

Synthetic stone SMT full process carrier has 3 grades: high (gray), medium (black) and low (blue).  Price sequence is gray, black and blue.  From past experience, synthetic stone and clear high temperature fiberglass has less cumulative deformation.(but synthetic stone has dust power problem and cannot be used in clean room).  Aluminum alloy has endothermic problem.  But the problem is solved, so it is good asset.Foggy high temperature fiberglass is not suitable for SMT full process, and suitable for REFLOW.  FR4 has most cumulative deformation,so it is also not suitable for SMT.

合成石SMT全製程載具. 依產品等級分: 最優(灰色)>次優(黑色)>普及(藍色). 價格也是依序灰>黑>藍. 目前累積經驗值中; 合成石與亮面耐高溫玻纖板的累積變形量最少(但合成石有粉塵問題無法於無塵室使用);  鋁合金雖有吸熱問題,但是以經驗克服後,是最實惠的生財器具.再次為霧面耐高溫玻纖板(不建議使用於SMT全製程,僅適用於REFLOW); 累積變形量最多為FR4,所以不適用於SMT.
