1、 Customer consultation scenario restoration
Customers often ask, ‘How do we charge for SMT small batch production?’? We can only reply with ‘expensive’. When customers request processing of 20-30 pieces, they often question the quotation: ‘Why is the quotation several times higher than what can be done for a few hundred yuan?’? This psychological gap often leads customers to give up cooperation.
2、 The Four Major Cost Components of SMT Small Batch Production
- Basic material cost:
Including consumables such as solder paste and red glue - Equipment depreciation cost:
Maintenance costs for SMT/reflow soldering equipment - Labor operation cost:
Working hours for line replacement debugging, quality inspection, etc - Cost of specialized fixtures:
Steel mesh production cost
3、 Industry quotation rules
The regular SMT quotation is calculated based on solder joints, but for small batch orders, attention should be paid to:
-Minimum startup fee: equipment debugging, preheating and other costs
-Special process surcharge: BGA or special processes may also increase production costs
-Material management fee: There may be other costs associated with purchasing external components
4、 The fundamental reason for the difficulty in cost allocation
10 pieces and 10000 pieces require the same production process:
- Production line debugging (1-2 hours)
- First article confirmation (30 minutes)
- Material preparation (30-60 minutes)
- Equipment cleaning (15 minutes)
Producing 20 pieces actually only takes 15 minutes to assemble, but the initial preparation time exceeds the assembly time by 3-4 times.
5、 Professional solution suggestions
Choose a factory equipped with a professional prototype line:
-Dedicated fast line changing system
-Small scale production equipment
-Standardized Material Management System
The cost of SMT small batch orders in such factories can be reduced by 40%, and the delivery time can be shortened to 24 hours.
