Contract Manufacturing Service

Customers are to dispatch printed circuit boards (PCBs) and components to us. We will assemble the entire order by leveraging state - of - the - art automated PCB assembly equipment.

Provision of Component Classification

It is advisable that customers supply additional components when releasing materials, as consumption may occur during the PCB assembly process. Although we anticipate minimal losses, for the sake of prudence, we highly value the availability of a small quantity of spare parts to preclude any potential delays.

Passive Components

• For components sized 0603 and larger: Incorporate a 20% damageallowance along with an extra 20 pieces.

• For components sized 0402 and 0201: Incorporate a 100% damageallowance along with an extra 100 pieces. A continuous tape is requisite.

• For all other material types: Incorporate a 20% damageallowance.

Integrated Circuits

• For those with a unit price below USD 1.00: Provide a 20%damage allowance.

• For those with a unit price ranging from USD 1.00 to USD 5.00:Provide 1 spare piece.

• For those with a unit price above USD 5.00: No damage allowanceis necessary.

Components with anti - static protection and moisture - sensitive device packaging will be handled with utmost care during inventory and storage procedures. Any unutilized components will be returned to the customer.

In most instances, upon receipt of the consigned kit materials, a rigorous incoming material inspection will be executed. The inspection report will typically be furnished within 24 hours of material receipt. However, on occasion, due to pressing production exigencies, issues may only be detected during the assembly process, following which feedback will be provided to the customer.

Bare PCBs

It is recommended that PCBs be equipped with a silkscreen layer denoting polarity and the first - pin position.

Special Handling Requirements

In the event that the kit is incompatible with detergents or has other special handling prerequisites, customers are required to submit special handling instructions or an operation manual.

Parts Procurement Policy

• Full Turn - Key Orders: 988 willperform procurement activities in accordance with the Bill of Materials(BOM) furnished by the customer. All substitution requests are subject tocustomer approval.

• Partial Turn - Key Orders: 988 willperform procurement activities based on the BOM provided by the customerand/or the components listed in the consigned procurement list. Allsubstitution requests are subject to customer approval.
