Thermal Defect Attribution Models for Mixed Consigned and Turnkey Boards
Thermal defect attribution in mixed consigned assembly requires combining profile logs, 3D X-ray data, and MSL handling records to split material and process liability.
Risk Allocation Matrix
Liability Division
A structured document used in project management assigns specific manufacturing and financial risks to either the buyer or the supplier. For custom board fabrication projects, a risk allocation matrix defines who is responsible for material price hikes, design errors, or transit damage. This clear boundary of liability prevents prolonged disputes and ensures that each party manages the risks they are best equipped to handle.
Procurement Process
Contracting parties use this tool during negotiations to align their expectations and establish clear operational procedures. A completed risk allocation matrix helps both the buyer and the fabrication house prepare for potential disruptions by assigning ownership of each risk. This includes detailing the financial consequences of board failures discovered during assembly and identifying who bears the cost of rework.
By defining these terms in advance, the procurement process becomes more transparent and efficient, reducing the likelihood of legal conflicts. The document is updated throughout the contract lifecycle to address new risks that may arise during ongoing production runs.
Assembly Defect
Technical risks, such as board warping or trace delamination, are assigned to the party that possesses direct control over the process or design. Incorporating a risk allocation matrix in the supply contract ensures that fabrication defects are addressed promptly by the manufacturer according to agreed protocols. This minimizes production downtime and ensures that corrective actions are implemented without delay.
