PCB Assembly cost, every electronics engineer or designer wants to know how to get the best quotation for PCB assembly and how price affects PCB assembly cost. Here are some tips on how to control PCB assembly prices.

First, clearly understand the attributes of PCB assembly (PCBA) costs. Some of the biggest cost drivers include:

(1) Assembly type Surface Mount (SMT) (SMD component) Through hole (DIP) mix (both)

(2) Component placement only requests the top-level component to request Doulbe double-sided assembly

(3) Total components (SMD + DIP)

(4) Component package size 1206 0804 0603 0402 020101005

(5) Component packaging (reel priority) Reel pipe tray belt or cut strip loose packaging bag without lead belt

(6) SMT SMT through hole automatic insertion through hole sliding line wave soldering automatic optical detection (AOI); br> X – ray selective solder manual solder assembly

(7) Quantity and batch size

“Keep Panelize flexible to meet your manufacturer’s needs.”

You need to ensure that panelization is optimized for the needs of PCBA manufacturers.

(8) Special parts preparation requirements (i.e., lead length, minimum/maximum height, spacing)

(9) Total cost of complete Bill of Materials (BOM)

(10) Number of bare board (PCB) layers and materials used

Flexible PCB components cost more than rigid PCB boards

(11) Coating requirements (medical or military usually require full coating or selective coating) Spray or brush coating Quantity of coating – Coating tolerance specified coating area

(12) Potting requirements (if any)

(13) Assembly compliance requirements RoHS (lead-free) Non-ROHS (leaded) IPC-A-610D Class I, CLASS II or Class III ITAR

(14) Test requirements (RayMing would prefer to test all PCBA boards before shipment, we would like you to tell us how to test) Power-on functional circuit test (ICT) Cycling no test (visual inspection only)

(15) Transport requirements standard ESD (electrostatic discharge) bags non-standard/special containers

(16) Delivery (RayMing provides fast rotating PCB assembly service)

Standard steering, no rush request Rush fast conversion (labor and material costs affected)

This 16 tips will affect the price of PCB assembly, so you can choose the best one to save the cost, when you purchase parts, you can provide source of multiple components for each component, it is easy to control some costs, not only from digikey, some agents also have a strong price support a component, more quickly to reduce cost

Set up a process to get low-cost resources between your design engineering and procurement departments. This is easier said than done. Conflicting priorities between design engineering and procurement can hinder this process.

One solution is to set up material cost reduction committees. Management works with procurement and engineering to identify high-value cost reduction opportunities. They also work to identify strategic components that require multiple sources to ensure continuous production.
