Electronic assembly SMT, THT

Our assembly offer is addressed to companies and institutions, which are looking for a comprehensive service in the electronic production field. As a part of an order we can acomplish the following operations:

1. initial, preparation actions
   • • printed circuit boards (PCB) and components picking – including purchase of difficult to access components (e.g. integrated circuits (ICs), which came out of production)
     • manufacturing of a stencil for paste application

   (we prefer laser cut stencils because of their better quality)

2. manufacturing activities
   • surface mounted assembly (SMD)
   • complementary through hole installation (THT)
   • optical inspection
   • packets painting
   • cabling assembly
   • mechanical installation, including adjustment of housing etc.
   • depenalisation
   • tagging / labeling
3. start up and testing
   • software saving on microcontrollers and CPLD/FPGA systems
   • functional tests – including testers provided by Customers or designed and made by us
4. advanced testing – needed in a limited number of cases
   • AOI test (Automatic Optical Inspection) – thanks to this test, the vast majority of assembly errors, which may be unobserved by imperfect human eye, is captured
   • X-RAY control(„roentgen”)– thanks to this verification we can control soldering quality in the areas, where AOI tester is not effective, e.g. short circuits can be verified / cold solders in BGA etc.
5. others
   • washing
   • packing (antistatistic protection)

Technological capabilities of SMD assembly:

• minimal size of discrete component 0402,
• integrated circuits and connectors – minimal pitch 0.4mm,
• uBGA, BGA, QFP, MLF, PLCC

We usually use the following materials to complete an order:

• lead-free paste S3X48-M406-3(prod. Koki)
• lead paste SS48-M955 (prod. Koki)
• no-clean fluzes (prod. CYNEL, Koki)
• tin Sn96,5Ag3Cu0,5 (prod. CYNEL)
• laser cut steel templates , or where it is economically reasonable and does not impair assembly quality, chemically etched or laminated, drilled steel templates

Obviously, if a Customer requests, we can use other materials specified by them.
