industrial control converter circuit board pcb

Industrial control converter pcba craft features:

1. Product code: SX2302B0-PCBA

2. Material / plate thickness: 94HB FR4

3. Insulation resistance: 10KΩ-20MΩ

4. Surface coating : chemical immersion gold

5. craftsmanship: solder paste lead-free

6. Process flow: smt+dip

7. Is there a gold finger welding pad: none

8. Need hand soldering, hand washing pcb

9. Minimum SMT spacing: 0.15mm (6mil)

10. SMD minimum package: 0206

Product craft special requirements:

1. The DIP welding pads are round or oval pads and must not have other shaped welding pads.

2. When the gap between the SMT component and the plug-in component cannot reach over 5MM and the furnace carrier cannot be fabricated, the plug-in component and the SMT component are designed on the same side of the PCB board, so that the used furnace can be omitted vehicle production.

3. If there is a filter capacitor on the PCB, it is necessary to evaluate whether the output voltage of the transformer and the withstand voltage of the filter capacitor are reasonable (such as output 12V, filter capacitor, 16V is not available; since the 12V rectifier filter is 16.9V, the filter capacitor need to be greater than 16V).

4. Do not allow missing parts, multiple pieces, wrong parts, reverse stickers, tombstoning, virtual welding, empty welding, continuous welding, cold welding, etc., which seriously affect the performance of the product.

5. Other defects that affect the appearance and function of the product.
